A sisterproblem to the socks problem is the following:
I found a sale where I could buy sneakers really cheap. So I bought a dozen. Same size and same colour: white. I spearated each of them to individual choes an put them in a box.
The next day I wanted to have a pair, but the light was out and it was dark as a coalmine. Anyway i thought that
If I take up x number of shoes (all undistinguashable by hand) how many would I have to take in order to be sure that I got one left and one right one?

Originally posted by MeadowsI controlled very carefully that in each pair there were one left and one right shoe. That was not the reason I got them so cheap. However, each pair were all white, and identical to eachother.

Ok (unless I'm missing a cheeky loophole or something foolish on my part), if you take n shoes, n/2 being left shoes and n/2 being right shoes, you need n/2 + 1 to guarantee that you'll have at least one of each.
In your case you bought 12 so I would presume that you need 7 boxes.

It's dark (as in a coal mine) and I pick up x number of shoes. What is x in order to be sure that I pick up a pair that I can use for my daily promenade?
No loophole and one box only. How many shoes do I need to pick up?
