If A and B are any two sets, find the number of elements in the set `A nn(A uuB)^c`

If A and B are two sets, then A nn (A uu B) equals

The set A nn A’ is:

If a set P has n elements, then the number of elements in the power set P is:

If two sets A and B are having 99 elements in common, the number of elements common to each of the sets A xx B and B xx A are 121 lambda^(2) , the value of lambda is

The number of subsets of the set {a, b} is :

If A and B are any two sets, prove that : A-B =A nn B^(c) .

The total number of subsets of a finite set A has 56 more elements then the total number of subsets of another finite set B. What is the number of elements in the set A ?

If X and Y are two sets, then X nn (Y nn X)' equals
