On two 6-sided fair dice:
- Rolling a sum of 5: 4 out of 36, or 11.11%
- Rolling a sum of 7: 6 out of 36, or 16.67%
- Rolling a sum of either 5 or 7: 10 out of 36, or 27.78%
Here's why: Look at the dice as unique, (maybe one is red and one is blue). Then there are 36 different possible outcomes.
- The four that give a sum of 5: 1+4, 2+3, 3+2, 4+1.
- The six that give sum of 7: 1+6, 2+5, 3+4, 4+3, 5+2, 6+1
So there are 4 chances out of 36 (or 1 out of 9 = 11.11%) to get a sum of 5, and 6 chances out of 36 (or 1 out of 6 = 16.67%) to get a sum of 7. If you want either 5 or 7 as a sum, add the chances together to get 10 out of 36 (or 5 out of 18 = 27.78%)
