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!!
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.
7 gloves
ReplyDeleteNah, just 3. If you grab 2 you may have one of each, so the third would have to complete a pair of one color.
ReplyDelete3 is the right answer
ReplyDeletelol i thought 3 then said 2 because it said in complete darkness so i thought it wouldnt count.. i know im weird!!
ReplyDelete7. 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
