At Tampa Bay Shopping Mall 100 shoppers were interviewed. 55 had Master Card, 40 had Discover Card and 15 had both cards. An individual from this group is selected at random. Let M be the event the person has a Master Card and let D be the event the person has a Discover Card. 1. Find the probability of getting a person having a Master Card and a Discover Card. 2. Are M and D mutually exclusive? Justify. 3. Compute P(DIM). 4. Compute P(D). 5. Using the results of parts 3 & 4 of this problem, state whether M and D are independent events. Justify 6. Compute P(D or M).
