Solution

What is the probability of rolling a sum of 9 when two dice are tossed?

Solution

\frac{1}{9}

Solution steps

The possible outcomes when two dice are rolled are

6 \cdot 6

Therefore, the number of possible outcomes:

6^{2}

Find the number of favorable outcomes of rolling a sum of 9 when 2 dice are tossed:

4

Probability

= \frac{number of favorable outcomes}{total number of outcomes}

= \frac{4}{6 ^{2}}

\frac{4}{6 ^{2}} = \frac{1}{9}

= \frac{1}{9}
