K The following table shows the distribution of murders by type Weapon of weapon for murder cases in a particular country over the Handgun past 12 years. Complete parts (a) through (e). Rifle (a) Is the given table a probability model? Why or why not? Shotgun Unknown firearm Knives Hands, fists, etc. Other Probability 0.474 0.027 0.033 0.143 0.134 0.057 0.132 OA. No; the probability of all events in the table is not greater than or equal to 0 and less than or equal to 1. OB. No; the sum of the probabilities of all outcomes does not equal 1. OC. 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. (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. D OA. If 1000 murders were randomly selected, we would expect about of them to have resulted from a rifle or shotgun. OB. If 1000 murders were randomly selected, exactly of them would have resulted from a rifle or shotgun. (c) What is the probability that a randomly selected murder resulted from a handgun, rifle, or shotgun? P(handgun, rifle, or shotgun) = (Type a decimal rounded to three decimal places as needed.)
