Question

In a single throw of two dice,find the probability that sum of two face is 7 or 11?

Answer 1

Answer:

There are 6 ways to throw 7, 1&6, 6&1, 2&5, 5&2, 4&3 and 3&4. So, 8 combinations could produce 7 or 11. The probability of not throwing a 7 or 11 is therefore 28 out of 36 or 7 out of 9.
