Probability

[erod09]

A certain brand of grass seed has a .86 probability of germination. If a lawn care specialist plants 9,000 seeds, find the number that should germinate.


I thought I was suppose to use the Permutation formula but the number is way too big when I I put .86P9000

The question is confusing
what is the probability all 9000 germinate?
[.86]^9000

what is the probability that n germinate?
nC9000 [86]^n [.14]^(9000-n)

Did your question mean what is the mean value of the number that generates
mu=npq
average=[.86][9000][.14]
I think that is the mean, but not sure

I am not sure but I know we are not looking for the mean. I am thinking I need to multiply the 9000 by .86
