**Reiny**, Thursday, November 14, 2013 at 9:00pm1. prob = (1/6)(1/6) = 1/36

2. the colour does not matter

there are 4 ways to get a sum of 5

(1,4) (2,3) (3,2) (4,1)

prob = 4/36 = 1/9

3. Again, what does the colour have to do with it?

prog(no 6 showing) = (5/6)(5/6) = 25/36

prob(at least one 6) = 1 - 25/36 = 11/36
