Given two sets P and Q such thatP={x:x is a natural number between 10 and 16}Q={y:y is a even number between 8 and 20}Find P−Q
Let P and Q be two finite sets such that n(P – Q) = 20, n(P U Q) =95, n(P ∩ Q) =35, then n(Q – P) is
If P and Q are two sets such that P has 40 elements, P∪Q has 60 elements and P∩Q has 10 elements, how many elements does Q have ?
