If the cardinality of a set A is 4 and that of a set B is 3, then what is the cardinality of the set AUB?

If the cardinality of a set A is 4 and that of a set B is 3, then what is the cardinality of the set A Delta B ?

Let A be the set of all 3xx3 matrices of whose entries are either 0 or 1. The number of elements is set A, is

Statement-1: If A and B are two sets having 3 and 5 elements respectively, then the total number of functions that can be defined from A to B is 5^(3) . Statement-2: A function from set A to set B relates elements of set A to elements of set B.

If A = { 1,2,3} , then the elements in its power sets, is
