White Select

A bowl contains 13 green balls and 16 white balls. I want to select 5 balls at random without replacement?

Find the probability that at least one of the 5 balls selected is green. Report your answer with 3 decimal places.

The best way to do most questions which ask for probability of at least 1 is by first doing probability of 0.

P(no green) = (16/29)*(15/28)*(14/27)*(13/26)*(12/25)
P(at least 1 green) = 1 – P(no green)

Can you finish it now? Result is between 0.96 and 0.97
