No; the probability of all events in the table is not greater than or equal to 0 and less than or equal to 1, and the sum of the probabilities of all outcomes does not equal 1. OB. No; the probability of all events in the table is not greater than or equal to 0 and less than or equal to 1. C. No; the sum of the probabilities of all outcomes does not equal 1. D. Yes; the rules required for a probability model are both met. (b) What is the probability that a randomly selected murder resulted from a rifle or shotgun? P(rifle or shotgun) = (Type a decimal rounded to three decimal places as needed.)
