Homework Help: Discrete math

Posted by Genie_math on Wednesday, October 3, 2012 at 8:49pm.

I need to find the coefficient of x^18 y^32 in (x+y)^50.

I understand that we have to use the binomial theorem. I know how to
find the coefficient for example x^18 but here we have "x" as well as
"y" which I have no idea about.
