In order to roll a 12 you have to roll a 6 on each die
The odds of rolling a 6 on the first one is 1/6, the same on the second. This comes out to a 1/36 chance of rolling a 6 on both of them together.
With a seven it does not matter what is rolled on the first one. 1-6 will still allow you to get to seven with the roll of the other one. That means you are only concerned about one of them and the chance is 1/6 that it will hit the right number to add up to 7
