Question

In a large metropolitan area, past records revealed that 30 percent of all the high school graduates go to college. From 10 graduates selected at random, calculate the probability that none will go to college.

Answer 1

70% of the students or 7 in 10 students won’t go to college.

This is because this is a subtracting problem.

10 - 30% = 7 or 10 - 3 = 7
