You roll a dice. What is the probability the sum of the first roll is 7 and the sum of the second roll is 10?
-----------------
To get a 7: 1,6;2,5;3,4;4,3;5,2;6,1
Prob(sum = 7) = 6/36 = 1/6
------------------
To get a 10: 4,6; 5,5; 6,4
Prob (sum = 10)= 3/36 = 1/12
--------------------
Prob(sum is 7 and sum is 10)= 1/6 * 1/12 = 1/72
