Kevin is trying to find a brown sock in his drawer. He has 16 white socks, 4 brown socks, and 6 black socks. What is the probability that he pulls out either a black or white sock, puts it back and then pulls out a brown sock?
There are a total of 22 black or white socks out of a total of 26 socks.
The probability of pulling out either a black or white sock is 22/26.
Since this sock is replaced, the probability of then pulling out a brown sock is 4/26.
To find the total probability, multiply these together: (22/26) x (4/26) = answer
