Answer:

7/36

Explanation:

It can be helpful to make a chart similar to the attached that lists all 36 possible outcomes from the roll of two dice.

You can see there are 4 ways to roll a sum of 5. There are 2 ways to roll a sum of 11, and 1 way to roll a sum of 12.

Getting a sum of 5, 11, or 12 on a roll of 2 dice can be achieved 4+2+1=7 of the 36 ways the dice can fall.

P(5, 11, or 12) = 7/36
