Question

If the graduation rate is 65% and 5 students are picked at random, what is the probability that 2 will graduate?

Answer 1

Binomial Probability

prob of graduation is .65
prob of not graduating is .35

P(2G) = C(5,2) * (.65)^2* (.35)^3 where C(5,2) indicates the number of ways to select 2 from a group of 5.

P(2G) = .1811
