If you toss a pair of dice 1,000 times, how many times would you expect to get a sum of 12 as the result. When you toss a die there is 1/6 probility that you will get 6 so if you toss another die the probability is the same. The get a sum of 12 the probability is 1/36.

So if you toss 1000 times,

You will get about 1000 (1/36) = 27 times
