Question 80914This question is from textbook A survey of mathematics with applications
: An artist entered two paintings(lighthouse, and Old catherdral) in the show. He feels that the probablities are 0.15, 0.18, 0.11, respectively, that he will sell the lighthouse, the old catherdral, or both. What is the probability that he will sell either of the two paintings?

You can put this solution on YOUR website! An artist entered two paintings(lighthouse, and Old catherdral) in the show. He feels that the probablities are 0.15, 0.18, 0.11, respectively, that he will sell the lighthouse, the old catherdral, or both. What is the probability that he will sell either of the two paintings?
-----------
Formula: P(A or B) = P(A) + P(B) - P(A and B)
-----------------
Your Problem:
P(lighthouse Or cathedral) = 0.15 + 0.18 - 0.11) = 0.22
