Question

What is the probability of rolling a sum of 8 on at least one of two rolls of a pair of number cubes?

Answer 1

P(At least one sum of 8) = 1 - P(No sums of 8)
 
P(At least one sum of 8) = 1 - (1 - 5/36)^2

P(At least one sum of 8) = 1 - (31/36)^2

P(At least one sum of 8) = 1 - 961/1296
 
P(At least one sum of 8) = 335/1296
 
So the answer is choice B
