Hi Dana,

One strategy is to make a systematic list of all possibilities and to pretend
you are working with two different colored number cubes. I'll pretend I have
a red number cube and a yellow number cube.

I'll record them as ordered pairs:  (R, Y).    
(1,1); (1,2); (1,3); (1,4); (1,5); (1,6)
(2,1): (2,2); ...

Assuming that you are systematic in your thinking and recording, you'll find
a total of 36 possible outcomes. Of the 36, 11 outcomes have at least one 6.
