I want to solve it, just walk me through it:)
Assume you are rolling two dice; the first one is red, and the second is green. Use a systematic listing to determine the number of ways you can roll a total less than 12 on the two dice.
In how many ways can you roll less than 12?
you want a total less than 12. Cool.
So, how many ways can I get it?
all except 6,6 i.e. when both dice have 6 on their face.
so, one outcome is unfavorable out of 36 possible ones.
whaddya think now?
