OK, question, if you have a bag with fifty black socks, and fifty white socks in it, whats the maximum amount of socks you have to pull out to GUARANTEE a matching pair?

Happy Thinking

Hi Dan,

If you are lucky you only have to pull 2 socks out, you have 2 black or white socks. Or you have one of each, so on your third pull you will have a matching pair of socks. On you third pull you will have 2 black socks or 2 white socks. No one can dispute this answer it is mathematically correct. It took a thousand times longer to type the answer than it did for me to have the answer. Try me again!!

All the best,
Jason.

Perception...................what's a match ?  To most it's two of the same colour, but to my daughter, it's the first two she comes across, gets a kick out of being slightly wacky, fortunately, it only extends to socks and it's her harmless way of " not quite conforming "

I imagine the roulette players would immediately have answered 51.

Hi Guys

Karl you read the question right but got the wrong answer.

I went for 3 which is the minnimum, the maximum is 51.

Cheers

Doug

Well done those who said 3, as, yes its, 3. Jason Hedges answered it most comprehensively so a litre of Cillet Bang goes to him in the first class post....

So one pull gets u either a white or black, the next? could be an odd one of the one you've already pulled, BUT the third is guarenteed to match one or the other you previously took out the bag.

Anyway, its a good one.
