Probability problems that require obtaining a favorable outcome in each of the given events are ________ probability problems.

The manager at the local auto shop has found that the probability that a car brought into the shop requires an oil change is 0.81, the probability that a car brought into the shop requires brake repair is 0.19, and the probability that a car requires both an oil change and brake repair is 0.19. For a car brought into the shop, determine the probability that the car will require an oil change or brake repair.
 Consider the figures to the right. Assume that one number from 1 to 7 is equally likely to be selected at random. Each number corresponds to one of the seven figures. Determine the probability of selecting an odd number, given that a

A television network, Network A, is scheduling its fall lineup of shows. For the Tuesday night 8 p.m. slot, Network A has selected its top show. If its rival network, Network B, schedules its top show during the same time slot, Network A estimates that it will get 1.4million viewers. However, if Network B schedules a different show during that time slot, Network A estimates that it will get 1.7 million viewers. Network A believes that the probability that Network B will air their top show is 0.3 and the probability that Network B will air another show is 0.7. Determine the expected number of viewers for Network A’s top show.
