You can turn this into an algebraic equation by changing the equation to -12 + x = -20. Our goal is to solve for x. This can be done by adding 12 to both sides. This gives us x = -8.

-12 + (-8) does equal -20.

If two 6-sided dice are rolled, what is the probability of rolling double 2s?

Komok [63]

16.7%

There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.
