Three socks 'make a pair'
A reporter for the Daily Mail has highlighted a way of using maths to one's advantage - by using the logical approach to matching socks.

Rob Eastaway said that if somebody wants to get a pair of socks or leggings out of the draw, they must get three as probability is much more in one's favour when using the "fun and functional" role of maths to find hosiery.

He used the example of three types of socks in a drawer - blue, black and white - and said that to get a pair, one simply has to get four out.

Mr Eastaway added: "With ten types of sock, you need to take out 11. The mathematical formula for this is: if you have N types of sock, you need to remove N+1 socks to guarantee a pair."

Fashion-wise, Georgea Kovanis of the Detroit Free Press said there were few things as comforting as a pair of socks.
