Question 510593
The probability that any given person is allergic to a certain drug is .03. What is the probability that none of the 3 randomly selected persons is allergic to this drug? Assume that all 3 persons are independent. 
---
P(allergic) = 0.03
P(not allergic) = 0.97
----
Since the condition for individuals is independent,
P(not allergic AND not allergic AND not allergic) 
= 0.97*0.97*0.97 
= 0.9127
