🎙️

What is the chance of rolling doubles on these dice?

There are 6 ways to roll doubles, our desired outcome, both ones, both twos, both threes, and so on.

And there are 36 total outcomes that are possible because each dice has 6 options.

So, our probability is 6 out of 36, or 1 out of 6. As a percent, that's 16.7%
