To determine the probability.

Answer to Problem 16PPS

Probability is $\frac{25}{36}$ or 69.4%

Explanation of Solution

Given information :

Rolling a pair of dice and not getting a 3.

Total possibilities while rolling a pair of dice are 36.

Probability of getting a 3 is $\frac{11}{36}$

(Either 3 comes on first dice with any number on second or vice versa. There shall be 11 outcomes.)

Now probability of not getting 3 is,

P(not getting 3) = 1- P(getting 3)

P(not getting 3) $=1-\frac{11}{36}=\frac{25}{36}$ or 69.4%
