Question

A packet of vegetable seeds has a germination rate of

90%. What is the probability that exactly 10 of 12
seeds planted will sprout?

Answer 1

N = number of seeds planted

P = probability of germination

K = number that germinated

Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k

p(10) = (12 10) x 0.90^10 x 0.10^2

P(10) = 0.2310
