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?
