On the final exam, there is a 41 percent chance that a randomly selected student will get a B or better. Make sure to answer completely ( define the variable, identify the distribution, show work, and answer in context) Would it be unusual to not get a B or better until test #8?

Suppose that I am working with 3rd period that has 25 students. How many B or better grades should I expect?

How many tests would I expect to go through to get to the first B or better?

I am personally hoping for seven B or better grades. Should I expect to be pleased with the scores or disappointed? Justify your answer.
