An artist entered two paintings (Lighthouse and Cathedral) ina show. He feels that the probabilities are 0.15, 0.18 and 0.11, respectively, that he will sell the Lighthouse, Cathedral, or both. What is the probability that he will sell either of the two paintings?
P(lighthouse) + P(Cathedral) - P(both) = 0.22
Note P(lighthouse) is the probability that the lighthouse will be solved, this includes selling the lighthouse and the Cathedral. This means that the possibility that both are sold is counted both in P(lighthouse) and in P(Cathedral), that's why you have to subtract P(both).
