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.

    If you toss 3 coins 10,000 times, how many times would you expect that exactly 2 heads appear?

    Tossing a die= 1/36 and so, the number expected of doing this 1000= 1/36 *1000=27.77777778 Approximately 28
