I know that this is a double post, but this question I posted 3 days ago currently has no answers. Here it is. Could someone please help me solve it?

Given a 50 card deck with cards numbered from 1 through 10 in each of 5 suits, how many 5 card hands are there that include exactly one pair of two cards that have the same numeric value?
