Mariko walks into her dark room to pull socks out of the dresser. If she has 5 pairs of white socks, 3 pairs of blue socks, and 4 pairs of pink socks that are single (not matched up), how many socks does she need to pull out to make sure she ends up with 1 matching pair?

Since there are three different categories, 4 must be drawn to be sure of getting a matching pair.

To match up 1 pair means i pair has 2 socks she has 1 she has t pull out i more to match up 1 pair

To match up 1 pair means 1 pair has 2 socks she has 1 she has to pull out 1 more to match up 1 pair

It would be thirteen.
