There are 32 socks in a bag consisting of 16 black socks and 16 white socks. What is the minimum number of socks you must take to make sure that you have three pairs of socks, where each pair has the same color?
Let's think of the extreme.
What if I took 5 black and 5 white socks out? Then the next sock to take out would have to make a pair.
So 5+5+1 = 11.
