Question 1158519: The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 65% of planted seeds will germinate. Suppose the manufacturer is correct. If 9 seeds planted with the fertilizer are randomly selected, what is the probability that more than 7 of them germinate?
Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.

This is 8 or 9 will germinate
for 9 it is .65^9+
for 8 it is 9*.65^8*.35, the 9 being 9C1 or 9 ways 8 germinations may happen
=0.1211 or 0.12
