A professor gives a list of 10 problems and tells his students that the exam will consist of 4 of the problems selected at random. If a student knows how to solve 6 of the problems, what is the probability that the student will make a perfect score on the exam?
What is the discrete probability distribution used for this problem?
Homework Answers
Hypergeometric
4 questions from 6 can be selected in 6C4 ways
Required probability = 6C4/10C4
= 0.0714

1. A statistics professor posted 10 review problems on probability distributions: 4 problems were on discrete distributions and 6 on continuous distributions. He then announced to his students that he will randomly select 3 problems out of those posted problems and use them on the midterm exam. Let X be the number of posted problems the professor ends up using on the exam that deal with discrete distributions. a. How many different selections of 3 problems are possible? b. Find...

16. From experience, a professor knows that the test score of students taking a final examination is a random variable with mean 65. A. Give an upper bound on the probability that a student's test score will exceed 75 B. Suppose in addition the professor knows that the variance of a student's test score is equal to 30. What can be said about the probability that a student will score between 55 and 75? C. How many students would have...
