Missy and Mussy are very messy sisters. Their dresser drawer consists of 43 white socks, 2 black socks, 23 blue socks and 8 red socks. What is the minimum number of socks they must remove from the drawer to be certain they have four socks of the same color?

Steve,
They might draw out 3 white, 2 black, 3 blue, and 3 red. After that, the 12th sock must be the same color as one of the others.
