Hi Guys

I need some help with a question below:
Three workers produce a certain part at the same rate .Joe averages 2 defective parts per hundred.Mary averages 5 defective parts per hundred.Harold averages 8 defective parts per hundred.The defective parts are identified by quality control and set aside in a rework pile.

How many defective parts do you expect there to be out of 1000 parts produced?

What is the probability that a randomly selected part in the rework pile was produced by Mary?
