Arithmetic never having been my strong point, I am at a loss as to how to work this out - and my husband, who knows about numbers, doesn't know either! What is the probability of rolling a total of 7 with 2 dice. Thankyou in advance for your help.

Amazingly, I have found an answer - 1:6 http://mathcentral.ur....09.97/thompson1.html
There are 6 ways to roll a 7 with the dice. There are 36 possible combinations. So the odds of rolling a 7 are 5-1. The probability is 1 in 6, or about 16%
Yep, 36 possible outcomes (first dice 1, second dice 1, 1&2, .....6&5, 6&6).

Six ways of getting a 7: (1&6, 2&5, 3&4, 4&3, 5&2, 6&1)

so probability of 7 is 6/36= 1/6
