Question

Two friends were each rolling a die. After they rolled, they found the sum of the numbers showing on each die. What is the probability that the sum is 7?

I added the sides together and simplified to get 1/6, but I don't think that's right.

Answer 1

The prob that you get a 7 when rolling two dice = 1/6

so when two friends roll , (the same result as you rolling twice)
prob(2 7's ) = (1/6)(1/6) = 1/36

Answer 2

thanks!
