I disagree with this answer...6 pairs of each color means that there are 12 black socks and 12 white socks in the drawer. To be garaunteed a pair, you would have to pull out 13 socks.
ppr1 is right, you pull the first sock its either black or white. You pull the second, its either black or white you might get lucky and get a matching pair. But to gaurentee a matching pair you have to pull three.
Say the first sock you pull out is white. Say the second sock you pull out is black. The next sock you pull out has to be either white or black. It's a guaranteed pair with one of the two socks you already have out. Its 3 socks people...
1st of all, good call Robert. 2nd, 3 is correct. i got it wrong, b/c i forgot that it asked for a matching pair of either sock color. i am an idiot, but, then again, look at my name.
lol, i thought the socks were paired together, so i thought, well, all she needs to do is pull out 1 pair. done. it didn't specify if they were separated
2 socks to make a pair
2 colors, black and white
1 black, then....
1 white (or another black, then Bingo! your pair) then...
1 black or white....your pair with ATMOST picking three times
24 socks
12 white
12 black
You pull one. Its either white or black.
You pull another. Its also either white or black.
You pull a third. No matter what socks you previously pulled, this sock MUST match.
Possible Results:
3 white.3 black.2 white and 1 black.2 black and 1 white.
Conclusion: Its impossible to have say, 1 black, 1 white, and 1 Unknown, as there are no unknowns,it has been stated that all are either white or black.
suppose you have 6 white socks, 6 black socks, and half the pairs were dirty.
Suppose you had a stuffy nose and complete darkness, how many socks do you need to get to guarantee a clean pair?
Actually, this is true. 13 is wrong becuase how could you pull 13 of two collours and not get 2 the same? same with 14.
therefore, 3 is right becuase if you pull out 1 white(w) and 1 black(b) the other would be b or w. you have a pair. if you pull out 22w and 1b, you have a pair. Get it?
are there really this many retarded ppl in the world...how can you think the answer is anything but 3..i am utterly disappointed with humanity after reading these answers
well it was very easy i barely had to think about it. the whole thing is probablity. you have to think probablity. that was what i did and i got right on my first try
If you only have two colors in your drawer, you will have a match by your third pull. It will be like 1 2 1, 1 2 2, 1 1 2, 2 2 1. Not really a fourth option.
My question is, if you cant see what color they are, what good does it to pull out a matching pair, unless you put on your socks outside after the sun has come up!
Unless the magical demons eat the other pair of socks and u never find them agian u will be left with nothing and then i will get my magical god farries to buy me more socks therefore i will have infinite sock =D i am so smart
OH!! ALSO WITH KAY
who says, the second one is different than the first one ?
you need 14
2 colors, black and white
1 black, then....
1 white (or another black, then Bingo! your pair) then...
1 black or white....your pair with ATMOST picking three times
12 white
12 black
You pull one. Its either white or black.
You pull another. Its also either white or black.
You pull a third. No matter what socks you previously pulled, this sock MUST match.

sounds suspisious to me
Suppose you had a stuffy nose and complete darkness, how many socks do you need to get to guarantee a clean pair?
betcha can't solve it.
it only took about 30 seconds
therefore, 3 is right becuase if you pull out 1 white(w) and 1 black(b) the other would be b or w. you have a pair. if you pull out 22w and 1b, you have a pair. Get it?

As you can see, there is a pair in all of the combinations.
It only took me about 5 seconds to solve this!
My question is, if you cant see what color they are, what good does it to pull out a matching pair, unless you put on your socks outside after the sun has come up!
