We are studying Le Chatelier's principle and I really need help thanks.. If you could also add the equation of the ions involved that would be great thanks a lot

I know the formula is n(A) + n(B) + n(C) - n(A intersection B) - n (B intersection C) n( A intersection C) + (intersection of A B and C) but I want to know what is the derivation of this formula thanks!

And how do you derive the cardinality of the n(U) given that set A is in U

Thanks A bunch!

She can be a great champion. And finally do you think that if she keep on improving can she win a grand slam title? If yes which one?
