A college student is taking statistics and wants to know what the probability of drawing marbles is. The only information the student has is the following.
There is a 14% that you will draw a blue marble. Also, 24% of those who draw a blue marble will get an "A" in the course.
Find the probability that the next student who draws a marble from the bag will
be blue and get an "A" in the course.

Candidates are applying for an elite college. From prior statistics we know that white students have an acceptance rate of 24% while Asian students have an acceptance rate of only 17%. A random sample of 100 White students and 100 Asian students were selected. Let X be the number of White applicants (out of the 100) who are accepted. Let Y be the number of Asian applicants (out of the 100) who are accepted. Question 1 of 4 Which of...
Hi. I am taking a course in college level statistics. I have a problem with an assignment in the "Sampling Distribution" chapter. It reads: Blood potassium levels*. Judy's doctor is concerned that she may have hypokalemia (low potassium in her blood, measured in millimoles per liter, mmol/l). There is variation both in the actual potassium level and in the blood test that measures the level. Judy's measured potassium level varies according to the Normal distribution with mean (μ) = 3.8...
