Do I change 65% into .65 and multiple it by 5? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Sixty-five percent of the students are under age 24. If 5 of these students are selected, what is the probability they are all 24 or older?

Binomial Problem with n = 5 and p = 0.35
----
P(x=5) = 5C5(0.35)^4(0.65)^0 = 0.35^5 = 0.0053
