Question

You roll a number cube twice. What is the probability of rolling a 2 first and then rolling an odd number?

Answer 1

1/12



The possibility of rolling a 2 is 1/6, since there is one option out of 6.

The possibility of rolling an odd number is 3/6, or 1/2, since half of the numbers are odd.

Multiply these two together by multiplying the numerators together and multiplying the denominators together.

(1 * 1) / (6 * 2)

1 / (6 * 2)

1/12
