Find `(PxxQ)`, if `n(Q-P)=10` and `n(P-Q)=13` and `n(PcapQ)=8`.

If n(P)=2 and n(Q)=5000, then n(PxxQ)= ______

If n(P)=17,n(Q)=10 and n(PcapQ)=8 , then n(P DeltaQ) is_____

If n(P) = 20, n(Q) = 18 and n(Puu Q) = 27 , then n(P - Q) =

If n(PcapQ)=12 and n(Q)=37 , then find the value of n(P'capQ) .

If n(P)=2439 and Q=phi then n(PxxQ)= ________

If P {x : x is a letter in the word CHANDIGARH } and Q = {x : x is a letter in the word JAMNAGAR }, then find n(P) , n(Q) n(P cup Q) and n (P cap Q)

If P and Q are two sets such that n(PcupQ) =75, n(Pcap Q) =17, and n(P) =49 , find n(Q) .

If n(PnnQ) = 23, n(PuuQ) = 57 and n(Q-P) = 26 , then n(P -Q) = "_____" .
