Sorry

This answer is incorrect.

The easiest way to look at this problem is to realize that each number on the dice has an equal chance of coming up. Therefore if you roll the dice 6 times each number will come up once. So if you roll the dice 3 times as often then each number should come up three times as often. So the answer in this case is 3.

Now let us try another one

If two dice are rolled 36 times, how many times will the sum of 12 be expected to come up?

• 1
• 3
• 4
• 5
