Probability Statistics

  1. There are 52 cars in a deck. A deck of cards is shuffled and the top two cards are placed face down on a table.

    1. (2 pts) What is the probability that the first card is an ace?

    2. (2 pts) What is the probability that the second card is also an ace (i.e., both are


    3. (6 pts) What is the probability that exactly one is an ace?

  2. (6 pts) An astronaut’s oxygen supply comes from two independent sources. Source A has a probability of 0.9 of working, and Source B has probability 0.8 of working. What is the probability that at least one of the sources is working?

  3. When traveling from New York, Plaxico Burress uses Laguardia Airport 50% of the time, Kennedy Airport 30% of the time, and Newark Airport 20% of the time. 99% of all guns are detected by security at Laguardia. 95% of all guns are detected by security at Kennedy. 80% of all guns are detected by security at Newark.

    1. (6 pts) What is the probability that Burress is using Laguardia if his gun has been detected?

    2. (6 pts) What is the probability that Burress is using Newark if his gun has been detected?

  4. In the 1980’s, Pennsylvania held a daily lottery. People would buy lottery tickets and try to guess which 3-digit number (000 through 999) would be picked. The winning lottery number was produced from three separate machines (one for each digit) that contained 10 ping-pong balls, labelled 0 through 9. The balls were blown about in a container by a jet of air and mixed. Then one was sucked through an opening at the top of the machine.

    1. (2 pts) What was the probability that the number drawn was 123 on any given day?

    2. (2 pts) What was the probability that the number drawn was 666 on any given day?

    3. (2 pts) On one day in April, 1980, the lottery number picked was 666. The next day, the Pittsburgh newspapers reported an unusually large number of tickets had been purchased for 666. This led to rumors that the lottery had

been fixed. A major concern was 666 was a “repeat-digit” number, i.e., all of the digits were the same. In 1000 drawings, how many repeat-digit numbers would be expected?

d. (6 pts) Later, some evidence suggested a hyperdermic needle had been used to inject paint into all of the ping-pong balls except those numbered 4 and 6 in all of the machines. As a result, when the balls were blown around by the jet of air, only those with 4’s and 6’s were light enough to be sucked out of the top of the machines. What was the probability of drawing 666 given that the lottery was fixed to produce 4’s and 6’s?

EDDL 614 Concordia University Cultural Bridgers Discussion

The Leader as a Cultural Bridger

Rosen (2003) argues:

Cultural bridgers are true integrators. They get excited seeing similarities and differences among people. Accepting that others may have different values than their own, they look for ways to discover those differences, destroy the walls between them, and celebrate their commonalities. They connect on some things and extract lessons from what’s different, always using the differences to build sturdier bridges. (pp. 174-175)

Do you agree or disagree with Rosen’s assertion?

Find a YouTube video, a TED talk, a poem, a song, or a journal article of your choice that supports your agreement or disagreement with Rosen’s assertion on “Cultural bridgers.” Include the link to your source.

  • In three to five paragraphs, describe your rationale for your selected source. Describe the demographics mentioned in the material and how these demographics might impact your leadership style or vice versa.

Support your statements with evidence from the Required Studies and your research. Cite and reference your sources in APA style.

PICOT Statement homework help

The first step of the EBP process is to develop a question from the nursing practice problem of interest.

Select a practice problem of interest to use as the focus of your research.

Start with the patient and identify the clinical problems or issues that arise from clinical care.

Following the PICOT format, write a PICOT statement in your selected practice problem area of interest, which is applicable to your proposed capstone project.

The PICOT statement will provide a framework for your capstone project (the project students must complete during their final course in the RN-BSN program of study).

Conduct a literature search to locate research articles focused on your selected practice problem of interest. This literature search should include both quantitative and qualitative peer-reviewed research articles to support your practice problem.

Select six peer-reviewed research articles which will be utilized through the next 5 weeks as reference sources. Be sure that some of the articles use qualitative research and that some use quantitative research. Create a reference list in which the six articles are listed. Beneath each reference include the article’s abstract. The completed assignment should have a title page and a reference list with abstracts.

Suggestions for locating qualitative and quantitative research articles from credible sources:

  1. Use a library database such as CINAHL Complete for your search.
  2. Using the advanced search page check the box beside “Research Article” in the “Limit Your Results” section.
  3. When setting up the search you can type your topic in the top box, then add quantitative or qualitative as a search term in one of the lower boxes. Research articles often are described as qualitative or quantitative.

To narrow/broaden your search, remove the words qualitative and quantitative and include words that narrow or broaden your main topic. For example: Diabetes and pediatric and dialysis. To determine what research design was used, review the abstract and the methods section of the article. The author will provide a description of data collection using qualitative or quantitative methods.

Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

can you help with my question?

  1. How do you believe the U.S. Supreme Court should rule—for or against Kibbe? Why? Use concepts from the text to support your response and opinions.

On a very cold night in Rochester, New York, Barry Kibbe and a friend met Stafford at a bar. Stafford had been drinking so heavily that the bartender refused to serve him more alcohol, so Kibbe offered to take him barhopping elsewhere. They visited other bars, and at about 9:30 p.m., Kibbe and his friend drove Stafford to a remote point on a highway and demanded his money. They also forced Stafford to lower his trousers and remove his boots to show he had no money hidden. Stafford was then abandoned on the highway, in the cold. A half-hour later, a man driving his truck down the highway saw Stafford standing in the highway, waving his arms for him to stop. The driver saw Stafford too late, and he was struck and killed. Even though the driver of the truck killed Stafford, Kibbe was arrested and charged with robbery and second-degree murder, raising a challenging question of causation—a necessary element in holding someone criminally responsible for a death.

State Court Actions: In State v. Kibbe, Kibbe was tried and convicted of robbery and murder in the second degree. At trial, the judge did not instruct the jury on the subject of causation (e.g., that the government had to prove Kibbe had actually caused Stafford’s death). On appeal to New York’s appeals court, in Kibbe v. Henderson, Kibbe argued that the judge should have given the jury such an instruction so that they would have to determine whether the state had proved this element beyond a reasonable doubt, but the appellate court affirmed his conviction. Then, on appeal to New York’s supreme court, the conviction was also affirmed. Both courts found that the judge did not err in failing to instruct the jury about causation.

Federal Court Actions: Having exhausted all possible state remedies, Kibbe then sought redress in the federal court, filing a writ of habeas corpus with the U.S. district court having jurisdiction and arguing that the trial judge had violated his due process rights by not giving the jury instructions regarding causation. The district court denied the habeas petition, saying that no constitutional question had been raised.

Next, Kibbe appealed to the Second U.S. Circuit Court of Appeals, making the same argument. This court, however, reversed his conviction, saying that Kibbe had been deprived of due process because of the trial judge’s failure to instruct the jury on causation. Next, the government appealed, this time to the U.S. Supreme Court; in Henderson v. Kibbe, the Supreme Court, issuing a writ of certiorari to the lower court, decided to hear the case.
