Consider a random experiment of rolling 2 dice. The sample space for rolling two dice is shown. Let S be the set of all ordered pairs listed in the figure. What is probability of rolling a sum larger than 10?


1/12 or 0.0833 or 8.3%
RATIONALE: The probability of rolling a sum of 11 corresponds to the event {(6, 5), (5, 6)} which is 2 out of 36 = 2/36.
The probability of rolling a sum of 12 corresponds to the event {(6, 6)} which is 1 out of 36 = 1/36.
Using the addition rule we add the two we have 2/36 + 1/36 = 3/36 = 1/12.
