I have the following story problem:
A professor is teaching a large class. He is going to break the class up into groups of 3. In the class, 53% of students have never taken a calculus course. 30% have taken 1 semester of calculus. 17% have taken 2 or more semesters. Question: What is the probability at least one of your group (of 3) have had more than 1 semester of calculus.
.17/3 = .056%
But, I think I am not including something.
