Joey's sock drawer is unorganized and contains 3 black dress socks, 5 black ankle socks, 7 brown dress socks, and 6 brown ankle socks. What is the probability that Joey will blindly reach into his sock drawer and pull out a sock that is brown or a dress sock?

I got 1/3 by doing: 13/21+10/21-16/21=7/21 which is 1/3 simplified. Is this correct?
