The following table shows the distribution of murders by type of weapon for murder cases in a particular country over the past 12 years. Complete parts (a) through (e). Weapon Probability Handgun Rifle Shotgun Unknown firearm 0.472 0.024 0.034 0.144 0.133 Knives Hands, fists, etc. 0.055 Other 0.138 (b) What is the probability that a randomly selected murder resulted from a rifle or shotgun? P(rifle or shotgun) = 0.058 (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. O A. If 1000 murders were randomly selected, we would expect about 58 of them to have resulted from a rifle or shotgun. O B. 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) = 0.530 (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. A. If 1000 murders were randomly selected, we would expect about 530 of them to have resulted from a handgun, rifle, or shotgun. OB. If 1000 murders were randomly selected, exactly of them would have resulted from a handgun, rifle, or shotgun. d) What is the probability that a randomly selected murder resulted from a weapon other than a gun? P(weapon other than a gun) = (Type a decimal rounded to three decimal places as needed.)
