# Question

The data from 200 machined parts are summarized as follows:

Depth of bore

Above Below

Edge condition Target Target

Coarse 15 10

Moderate 25 20

Smooth 50 80

(a) What is the probability that a part selected has a moderate edge condition and a below-target bore depth?

(b) What is the probability that a part selected has a moderate edge condition or a below-target bore depth?

(c) What is the probability that a part selected does not have a moderate edge condition or does not have a below-target bore depth?

(d) Construct a Venn diagram representation of the events in this sample space.
