A distribution center receives shipments of a product from three different factories in the quantities of 60,35 and 25. What is probability that none of the three products came from the third factory.

I have completed part a (Probability that all three products came from the third factory which is .008), but I'm a little lost with part B.:confused:

What is the Probability that one of the products came from factory 3? P1


What is the Probability that two of the products came from factory 3? P2

What is the Probability that all three of the products came from factory 3? P3

What is the Probability that none of the products came from factory 3? 1- (P1 + P2 + P3)
