From thousands of blue and black soxes, what minimum number of soxes to be picked to get a pair of same color?

Question

Supposing you have thousands of blue and black soxes (all free size) kept mingled in a box in a dark room (so that you cannot differentiate the color), and when you are in a hurry, how many minimum number of soxes you should pick up from the box to get you a pair of soxes of same color (either blue or black)?

Answer 1

3; 2 out of the three are always going to be the same colour. Assuming that none of them are faded of course :-)

Answer 2

3

Answer 3

My theory for the correct answer for this question is-- the minimun number is undeterminable because even though they are "mingled together" there could be a clump of say.eight blue ones together right where I deciede to take a handful from. Three is not the correct answer either because it would be like saying if you"d spread a deck of playing cards face down on a table and only picked up three--does that guarantee you"ll have 2 black + 1 red or

Answer 4

Why would I buy thousands of socks, and more to the point, why would I put them in a dark room?
My socks are in the sock draw in my bedroom, where there is ample light for ensuring the correct allocation of socks based on numbers and colour.
Finally, I am always in a hurry, but still manage to leave the house wearing amongst other things, a pair of clean matching socks........Hope this helps, you can be confident that I do not have a sock issue..
Thank you

Answer 5

2 is the minimum & 3 is the maximum

Answer 6

Grab three socks and you will have a pair of either blue or black. Been there, done that.

Answer 7

Well for one thing: "sock" is singular, "socks" is plural as in "a pair of socks" - second, I would just grab a handful and hope for the best.

Answer 8

obvious 3

Answer 9

clearly 3

Answer 10

just pick 3 socks and your guaranteed to find a pair!! xx
