Question
## Interpretation and Analysis of Murder Weapon Statistics The following information concerns the distribution of murders by type of weapon used in murder cases over the past 12 years. This data can be essential for criminological studies, policy-making, and law enforcement strategies. The table below provides the probability distribution of different types of weapons used in murders: | Weapon | Probability | |-----------------|-------------| | Handgun | 0.474 | | Rifle | 0.024 | | Shotgun | 0.023 | | Unknown firearm | 0.144 | | Knives | 0.135 | | Hands, fists, etc.| 0.056 | | Other | 0.135 | ### Exercises **(b) What is the probability that a randomly selected murder resulted from a rifle or shotgun?** \[ P(\text{rifle or shotgun}) = \, \_ \, \] _(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. - A. If 1000 murders were randomly selected, exactly \[ \_ \, \] of them would have resulted from a rifle or shotgun. - B. If 1000 murders were randomly selected, we would expect about \[ \_ \, \] of them to have resulted from a rifle or shotgun. **(c) What is the probability that a randomly selected murder resulted from a handgun, rifle, or shotgun?** \[ P(\text{handgun, rifle, or shotgun}) = \, \_ \, \] _(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. - A. If 1000 murders were randomly selected, we would expect about \[ \_ \, \] of them to have resulted from a handgun, rifle, or shotgun. - B. If 1000 murders were randomly selected, exactly \[ \_ \, \] of them would have resulted from a handgun, rifle, or shotgun. ### Explanation of Questions - **Question (b)** requires calculating the combined probability of murders resulting from either a rifle or a shotgun. This involves summing the probabilities associated with each weapon type. - **Question (c)** extends this to include murders involving hand
