Weapon Handgun Rifle Shotgun Unknown firearm Knives Hands, fists, etc. Other (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.) Interpret this probability. Select the correct choice below and fill in the answer box to complete your choice. Probability 0.475 0.028 0.031 O A. If 1000 murders were randomly selected, exactly of them would have resulted from a rifle or shotgun. O B. If 1000 murders were randomly selected. we would expect about of them to have resulted from a rifle or shotaun. 0.144 0.134 0.056 0.132 (a) Is the given table a probability model? Why or why not? O A. No; the sum of the probabilities of all outcomes does not equal 1. O B. No; the probability of all events in the table is not greater than or equal to 0 and less than or equal to 1. O C. 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. O D. Yes; the rules required for a probability model are both met. 0
