The following table shows the distribution of murders by type of weapon for murder cases in a particular country over the past Weapon 12 years. Complete parts (a) through (e). Probability Handgun Rifle Shotgun Unknown firearm Knives Hands, fists, etc. 0.472 0.024 0.034 0.144 0.133 0.055 Other 0.138 (a) Is the given table a probability model? Why or why not? O A. 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 B. 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. OD. Yes; the rules required for a probability model are both met.
