An oil company is bidding for the rights to drill a well in
field A and a well in field B. The probability it will drill a well in field A
is 40%. If it does, the probability the well will be successful is 45%. The
probability it will drill a well in field B is 30%. If it does, the probability
the well will be successful is 55%. Calculate each of the following
probabilities:
