You have a set of results in q7.png for the totals of rolling a pair of dice.  How would you calculate the probability of rolling a 6 from that data?  How would you calculate the same for a 9?  Then, how would you combine those two probabilities?

There is a more direct approach (eliminating the "how would you combine") but I don't know how to direct you there without giving too many details.

I'm not sure what your P=(5+4)/36....  is intended to show.  If you'd provide details on each of the numbers that would help if you want comments on it.

Your P=.... equation appears to be correct, but one needs to explain how you got there (or what the specific numbers mean).
