Question

What are the odds of rolling two number cubes and getting a sum of seven?

Answer 1

We assume that the two number cubes are six-sided and numbered from 1 to 6, AND that they are fair cubes.

Complete the table of outcomes and count how many 7's are in the table.
Divide by the total number of outcomes, 6\(\times\)6=36 to get the probability.

Answer 2

Oh, by the way, odds are the ratio between success and failure.
Suppose there are x successes, and 36-x failures, the odds are x:36-x, reduced to the simplest (integer) terms.
