if p = {-3<x<1} and Q = {-1<x<3}, where x is a real number, find P n Q.

consider the statements:

P = All students offering Literature(L) also offer History(H);

Q = Students offering History(H) do not offer Geography(G).

Which of the Venn diagram correctly illustrate the two statements?

The shaded portion in the venn diagram above represents?

If n(P) = 20 and n(Q) = 30 and n(PuQ) = 40, find the value n(PnQ)

Given that A and B are sets such that n(A) = 8, n(B)=12 and n(AnB) =3, find n(AuB).
