**Reiny**, Wednesday, April 22, 2009 at 9:46pmI think you are dealing with "conditional probability"

usually written as P(B│A) and read as

"the probability of B given A"

P(B│A) = P(A and B)/P(A)

= (1/8) / (1/5)

= 5/8

**Reiny**, Wednesday, April 22, 2009 at 10:08pmYou are dividing 2 fractions at the end

(1/8) / (1/5)

= (1/8) ÷ (1/5)

= (1/8)x(5/1)

= 5/8
