Think carefully!!

Cathy has six pairs of black gloves and six
pairs of brown gloves in her drawer.
In complete darkness, how many gloves must
she take from the drawer in order to be
sure to get a pair that match?
Think carefully!!

  1. Nah, just 3. If you grab 2 you may have one of each, so the third would have to complete a pair of one color.

  3. 7. with 3 you could have a three right handed black gloves. with 6 you could have 3 right blacks and three left browns (eg). THINK CAREFULLY

  4. If the L and R gloves are different then the last "Anonymous" is correct. There are 6 PAIRS of each colour so it is possible to pull 12 out and have (say) 6 L (or R) black and 6 L (or R) brown. The 13th glove will match one of those already drawn.

    If the gloves are like mittens, then 3 will be sufficient.
