Question 1191734
Here's how to calculate the probabilities:

* **Total participants:** 250

* **a) Favors tougher gun control laws:**
   * Number who favor tougher laws: 150
   * Probability: 150 / 250 = 0.6 or 60%

* **b) Owns a handgun only:**
   * Number who own a handgun only: 58
   * Probability: 58 / 250 = 0.232 or 23.2%

* **c) Owns a handgun:**
   * Number who own a handgun (handgun only + handgun and rifle): 58 + 0 = 58
   * Probability: 58 / 250 = 0.232 or 23.2%

* **d) Favors tougher gun control laws and owns a handgun:**
   * Number who favor and own a handgun: 0
   * Probability: 0 / 250 = 0

* **e) Opposes tougher gun control laws and does not own a handgun:**
   * Number who oppose and don't own a handgun: 5 + 25 + 0 = 30 (Rifle only + Handgun and Rifle + Owns neither)
   * Probability: 30 / 250 = 0.12 or 12%

* **f) Owns a rifle given they favor tougher gun control laws:**
   * Number who own a rifle and favor tougher laws: 12
   * Number who favor tougher laws: 150
   * Conditional Probability: 12 / 150 = 0.08 or 8%

* **g) Favors tougher gun control laws given they own a rifle:**
   * Number who own a rifle and favor tougher laws: 12
   * Number who own a rifle: 12 + 5 + 25 = 42
   * Conditional Probability: 12 / 42 ≈ 0.286 or 28.6%
