Question 395666: A biologist studying the germination rate of a seed finds that 90% of the seeds of a given type germinate. If she has a box of 10 seeds, what is the probability that exactly 6 of the seeds germinate?
Note: The probability of x successes in n trials is:
P = nCx* where p and q are the probabilities of success and failure respectively.
In this case p =.9 and q = .1
nCx =
P(out of 10, exactly 6 will germinate) = 210(.9)^6(.1)^4 = .0112
