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?

Answer 1

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.
