In testing a new drug, researchers found that 10% of all patients using it will have a mild side effect. A random sample of 14 patients using the drug is selected. Find the probability that:

(A) exactly two will have this mild side effect

(B) at least three will have this mild side effect.

Hmmmmmm.....not sure.....
