Question

What is the probability of getting a sum of 7 on a roll of two dice?


  1. 7/12

  2. 1/11

  3. 1/6

  4. 2/3


Solution

The correct option is C

1/6


There are six outcomes that give a sum of 7: (1,6), (2,5), (3,4), (4,3), (5,2) and (6,1).
Since there are 36 possible outcomes, the required probability is 636 = 16.
