Question 1157711: It is known that a certain drug causes side effects in 10% of patients. If we consider a random sampling of 12 patients, what is the probability fewer than two have the side effect?

Probability EXACTLY ONE has the side effect:
= 0.1 * 0.3138 * 12 = 0.3766
Probability NONE have the side effect:
= 0.2824
Probability FEWER THAN TWO have the side effect: 0.3766 + 0.2824 = 0.6590
