If a seed is planted, it has a 60% chance of growing into a healthy plant.

Question

If 10 seeds are planted, what is the probability that exactly 3 don't grow?

Answer 1

Binomial distribution is applicable here. x = number of successes, n = number of trials, p = probability of success for an individual trial. B(x,n) = C(x,n) p^x (1-p)^(n-x) = C(10,3) (0.6)^3 (0.4)^7.
