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.
