<PRE><B>Question 126060</B>
A local bakery determines that the probability of a customer ordering a blueberry muffin is 50%.  5 customers come into the bakery.
A.	What is the probability that 3 out of the 5 order a blueberry muffin?
P(x=3) = 5C3(1/2)^3(1/2)^2 = 10*(1/32) = 0.3125...
--------------------------
B.	Explain why this scenario would meet the criteria of a binomial distribution.
Two possible outcomes.
Selections are independent.
Constant probability of success
