$105
Step-by-step explanation:
$15 for one case of snicker bars. Since it's $30 for 2. He needs 140 so 140 divided by 20(which is in one case) = 7. So he needs 7 cases to have 140 snicker bars. Well, if each case itself is $15 and we need 7 cases. 7 times 15= 105. It's going to cost him $105 to fill that vending machine.
Answer:

Step-by-step explanation:

We could use the product rule of probabilities in solving this problem. For the first roll, the probability of getting an even number is 3 / 6 = 1/2. For the second roll, the probability of getting a 6 is 1/6. Multiplying both is 1/2 * 1/6 = 1/12.
