In a game two fair number cubes are rolled. To make the first move, you need to roll a total of 6, 7, or 8. What is the probability that you will be able to make the first move?

For anyone who saw the short gibberish before I got to the edit button - that was my cat answering (he actually posted the whole thing before I got to it).

Ok - on to the question:

Let's first see the possible die results:


There are 5 ways to roll a six, 6 ways to roll a seven, and 5 ways to roll an eight. That's 16 rolls that will allow for a first move.

There are 36 possible rolls.

This means that there is a #16/36=4/9~=44.4%# of being able to make a first move.
