sue, a botanist, is studying a new plant seed. if it is known that these seeds have a 95% probability of germinating. if sue plants seeds, what is the probability that; a) exactly four seeds will germinated? b) at least five will germinated? c) at most one will not germinated?
We need to know how many she planted.
Given n, use binomial distribution with p = 0.95 and 1-p = 0.05
