Question

An experiment consist of rolling Two fair number cubes. find the probability of each event.

9). P (total shown=3)

Answer 1

Probability = (number of possible successes) / (number of total possibilities).

Number of total possibilities:
Each cube can come up in 6 different ways.
Total number of possibilities = 6 x 6 = 36

Possible successes:
There are 2 different ways to roll a 3 . . .

1 . . . 2
or
2 . . . 1

The probability is 3/36 = 1/12 = 0.0833... = (8 and 1/3) percent
