What is the theoretical probability that you will get a sum of 7? P(sum of 7)=
hammer [34]

Answer:

\frac{12}{36} or \frac{1}{3}

The reason the answer is 12 and not 6 is that you need to double it for the two dice. Let's say one die was green and the other was blue. The green die could be the 1 and the blue die could be the 6. That is one favorable outcome, but it could be switched. Maybe the green die was 6 and the blue die was 1.
