Students take Test A and have a failure rate of 64% (pass rate of 36%). A class of 20 students take Test A. • Find the probability that everyone passes. • Find the probability that no one passes. • Find the probability that at least one person passes. • Find the mean • Find the variance

Step 1
Probability that everyone passes: Since the pass rate is 36%, the probability that one student passes is 0.36. Therefore, the probability that all 20 students pass is: Show more…

5. A statistics instructor has established that 10 percent of all students who take his course receive a failing grade. If 11 students have enrolled for his course next semester, a) what is the probability that more than three of these students will fail? b) determine the expected number of students who will fail and the variance. 6. Determine the mean and variance of a binomial random variable X for which n = 30 and p = 0.7.
