Mr. Blue has 12 brown gloves and 8 black gloves in a drawer in his closet. If he blindly pulls gloves from the drawer, what's the minimum number of gloves Mr. Blue will have to pick, to be certain he has a pair of gloves of the same color?
he draws one glove, 50% chance he draws the same color glove. if he draws the other color glove, his next draw ensures that he has two of the same.
