Question 1157871: It is known that a certain drug causes side effects in 12% of patients. If we consider a random sampling of 18 patients, what is the probability less than two have the side effect? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website!
for 0.12 probability of a side effect there is 0.88 probability of no side effect
0 side effects is 0.88^18=0.1002
1 side effect is 18*.88^17*0.1^1=0.2049
The answer is the sum or 0.3051
