Eight balls numbered 1 to 8 are placed in a bag. Some of the balls are grey and some are white. The balls numbered 3, 4, and 6 are grey. The balls numbered 1, 2, 5, 7, and 8 are white. A ball will be selected from the bag at random. The 8 possible outcomes are listed below. Note that each outcome has the same probability. 1 2 3 5 6 7 8 Complete parts (a) through (c). Write the probabilities as fractions. (a) Check the outcomes for each event below. Then, enter the probability of the event.
