Question

A single die is rolled twice. The 36 equally-likely outcomes are shown to the right. Find the probability of getting two numbers whose sum is 6.

Answer 1

5/36

Explanation:

All the probability of getting 2 numbers whose sum is 6:

36 total outcome probabilities

1+5 = 1 posible probability

5+1 = 2 possible probability

2+4 = 3 possible probability

4+2 = 4 possible probability

3+3 = 5 possible probability

∴Probability of getting 2 numbres whose sum is 6 = 5/36
