Question 427771
A pair of fair dice is rolled. What is the probability that the sum of the numbers falling uppermost is less than 9 given that at least one of the number is a 6?
-------
Pairs that meet the conditions: (6,1)(6,2);(1,6)(2,6)
----
Pairs with at least one 6: 
(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)
(1,6)(2,6)(3,6)(4,6)(5,6)
---
P(sum< 9|at least one 6) = 4/11
