If `n(P-Q)=x+37,n(Q-P)=30+3x,n(PuuQ)=120+2x` and `n(PnnQ)=35` , then x is:

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

If P={x:xlt3,inN}, Q= {x:xle2, inW} Then find (PuuQ)xx(PnnQ), Where W is the set of whole numbers.

If P={x:xlt3,inN}, Q= {x:xle2, inW} Then find (PuuQ)xx(PnnQ), Where W is the set of whole numbers.

If P= {x: x lt 3, x in N}, Q = {x : x le 2, x in W} then find (P uu Q) xx (P nn Q) , where W is the set of whole numbers.

A is a set containing 'n' elements . A subset P of A is chosen at random . The set A is reconstructed by replacing the elements of the subset of P, a subset Q of A is again chosen at random. Find the probability that (i) PnnQ=phi (ii) PuuQ=A (iii) PuuQ=A and PnnQ=phi (iv) Q is subset of P

If (p)/(x) +(q)/(y) =m and (q)/(x) +(p)/(y) =n , then what is (x)/(y) equal to ?
