S6xample 31 Two dice are thrown simultaneously. Find the probability that the sum of thenumbers appearing on the top of two dice is less than or equal to 10.

Answer»

Total number of outcomes when two dices = 6*6 = 36

Possible outcomes that sum is greater than 10= (5,6) (6,5) (6,6)

Probability that sum is greater than 10 = 3/36 = 1/12

Then, probability that sum is less than or equal to 10 = 1 - 1/12= 11/12
