Question 841958: Ryoko has 9 pairs of shoes. Of the pairs, 6 pairs are athletic. The rest of the shoes are dress shoes. If Ryoko selects a pair of shoes at random, which expression represents the probability that he will select dress shoes?
A 1 - 3/9
B 1 + 3/9
C 1 - 3/15
D 1 - 6/15
I understand that there is a 1 in 3 chance of picking dress shoes. How do I express this in an equation?
