here is another homework problem I am stuck on...

Let P(x.y) stand for the proposition that person x plays sport y. For example, P(babe Ruth, Baseball) is true.

Express symbolically, using P and the descriptor notation the set of sports exactly one of you and me plays (i.e., either you play it and I don't or I play it and you don't). Use my initials (JG) and your initials where needed in your expression.
