10:46 am - Brain teaser question
I was looking at a brain teaser quiz yesterday and read the question and potential answers below. I feel dumb, but I couldn't figure out what the question was actually asking. So I thought I'd ask you. What does the question mean? What's the right answer, and how did you get there?
Amy has five pairs of brown socks and five pairs of black socks in her drawer. In total darkness, how many socks must Amy take out of the drawer in order to be sure that she gets a pair that match?
