It's not d because you don't roll a 5 more than 50% of the time. It's not c because the probability of rolling a 7 is 1/6, and getting a 5 is less likelier than getting a 7, not more likelier. It's not b because that's 7's probability. It's not a because... I lied.

1/6. A pair of dice is 2 dice. Each dice has a 5 on it out of 6. 6 x 2 is 12. and 2 5's out of those 12 numbers gives you 2/12. Simplify that by dividing 2/12 which gives you 1/6. The answer is B.

There are 36 possible combinations of two six sided dice... They are... 1 1 1 2 1 3 1 4 1 5 1 6 2 1 2 2 2 3 2 4 2 5 2 6 3 1 3 2 3 3 3 4 3 5 3 6 4 1 4 2 4 3 4 4 4 5 4 6 5 1 5 2 5 3 5 4 5 5 5 6 6 1 6 2 6 3 6 4 6 5 6 6 How many of them add up to 5??? 1 4 2 3 3 2 4 1 4 out of 36 combinations have the sum of 5... 4/36 can be simplified down to 1/9... So the answer is a. 1/9

a combination of 5 can be reached four ways, 1&4, 4&1, 2&3 and 3&2. There are a total of 36 possible combinations when rolling 2 dice. therefore, 4/36, or 11.1% of the time a five will be rolled. this equates to 1/9.
