You can put this solution on YOUR website! Given a box with individual mittens as follows 2 purple, 6 red, 9 green, what is the probability of randomly drawing a matched pair?
----
# of matching pairs = 2C2 + 6C2 + 9C2 = 1 + 15 + 36 = 52
----
# of possible pairs 17C2 = 136
====
P(draw matched pair) = 52/136 = 13/34
