Matching pegs (Posted on 2016-06-08)

There are 20 garments on a clothes line each garment supported by two pegs.
The pegs were randomly picked out of a set of 20 green and 20 red pegs.

What is the probability that n garments are supported by two pegs of the same colour?

Provide a list for 21 possible values of n.
