A-set contains 4 elements. It’s power set will contain _______ element.

A set contains n elements.The power set contains

If set A contains p elements and set B contains q elements then their total number of reletions from A to B is-

If A is a finite set and contains n elements, prove that the power set of A has 2^n elements.

Let A be a set containing elements. A subset P of the set A is chosen at random. The set A is reconstructed by replacing the elements of P, and another subset Q of A is chosen at random. The probability that P cap Q contains exactly m (m lt n) elements, is

If f(x)+2f(1/x)=3x , x!=0, and S={x in R :f(x)=f(-x)} ; then S: (1) is an empty set. (2) contains exactly one element. (3) contains exactly two elements. (4) contains more than two elements

Define with examples: Power set

A set contains (2n + 1) elements. The number of subsets of the which contain at most n elements is

Two finite sets have m and n elements. The number of elements in the power set of first set is 48 more than the total number of elements in the power set of the second set. Then the value of m and n are-

Let S be a set containing n elements.Then the total number of binary operations on S is

In a set S contains n elements. Find the total no. of non void subjects of S.
