Asked by Andrew

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?

1.)about 12 times
2.)about 27 times
3.)about 36 times
4.)about 100 times

The lesson doesn't show me how to work this. Whats the formula?

the prob of getting 12 when tossing 2 dice = 1/36

so the number expected doing this 1000 times
= 1000 x 1/36 = 250/9
= 27.777

so it would happen approx 28 times.
