<PRE><B>Question 402586</B>
the probability that a person in the united states has AB+ is 3%. five unrelated Americans are selected at random.
---
Binomial Problem with n = 5 and p = 0.03
-------------------------- 
find the probability what all five have type AB+ blood? (0.03)^5
----------------------------- 
Find the probability that none of the five have AB+ blood?(0.97)^5
----------------------------- 
find the probability that one of the five has type AB+ blood?
P(x = 1) = 5C1(0.03)(0.97)^4 = binompdf(5,0.03,1) = 0.1328
