So |S| = 6^3 = 216.

My event set will be the combinations of the numbers on the 3 dice which sum to 7. So, E = {(1,1,5), (1,2,4), (1,3,3), (2,2,3)}

My condition is F = 1 was obtained on two of the dice given they sum to 3 = {(1,1,5)}

I'm not sure if I should do P(E|F) or P(E^F) as I'm kind of lost.

Could it be p(E)*p(F) which is (4/216) * [(1/4)/216]?
