Quick Answer: What is the probability of getting a sum of 4 dice?

How many outcomes are there with 4 dice?

My initial reaction is to say that the answer is 64, since 4 dice can have 6 outcomes.

What is the probability the sum of the four dice equals 7?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
