Question: 

A man opens a general store and a book shop. In any one year the probability of a robbery in the general store is 0.10 and the probability of a robbery in the book shop is 0.02. For any one year. What is the probability that:


1)Neither business will be robbed.
2)Either one or the other (but not both) will be robbed



Answer

a. Probability that neither businesses will be robed, P(G nor B)= 0.90 * 0.98 =0.88

b. Probability that Either one or the other (but not both) will be robbed = 0.10 + 0.02 - (0.10) (0.02) = 0.118
