Two dice are tossed together. The sum of the outcomes is noted. What is the probability that the sum is less than 7

Solution

\frac{5}{12}

étapes des solutions

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 the sum is less than 7:

15

Probability

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

= \frac{15}{6 ^{2}}

\frac{15}{6 ^{2}} = \frac{5}{12}

= \frac{5}{12}
