Question

You have a drawer with ten brown socks, ten black socks, and ten white socks. The room is dark enough that you can't see the socks, and they are otherwise identical, so they all feel the same. What's the minimum number of socks you must pull out of the drawer to be guaranteed a pair of matching socks?

Answer 1

Answer:

if we pull first black then white and then brown then fourth one is matching

so minimum drawings are 4
