I have 18 distinguishable socks in my drawer: 8 white, 6 brown, and 4 blue. In how many ways can I choose a pair of socks, provided that I get two socks of the same color?

Ways to choose 2 white =  C(8,2)  = 28

 

Ways to choose 2 brown = C(6,2)  = 16

 

Ways to choose 2 blue  = C(4,2)  = 6

 

So

 

28 + 16 +  6  =

 

50 ways

 

cool cool cool
