Two standard dice are rolled. What is the probability of the sum on the two dice being less than 10.
---------------
Draw the sample space which is
a 6 by 6 square with the sums listed:
2,3,4,5,6,7
3,4,5,6,7,8
4,5,6,7,8,9
...
...
7,8,9,10,11,12,
----------------------
Count the sums that are less than 10: 30
----------------------
P(sum less than 10) = 30/36 = 5/6
