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?
In gloves, the left and right glove are different. In order to be certain to pick a pair of gloves of the same colour, one has to pick 11 gloves from the drawer. Among the 11, the worst case could be 6 gloves of brown colour of
one hand, 4 gloves of black colour of one hand and an extra glove should become a definite pair of any of the other colour.
