A= (1,2, 3, 4, 5, 6), A`Delta`B= {1,7, 8), then the number of subsets of Bhaving at least one element,

If A={1,2,3,4,5,6} , then the number of subsets of A which contain atleast two elements is

Let A={1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Then the number of subsets of A containing exactly two elements is

Let A={1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Then the number of subsets of A containing two or three elements is

Let A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} . Then the number of subsets of A containing two or three elements is:

If A={1,2,3,4}, then the number of subsets of set A containing element 3 , is

If A={1,2,3,4}, then the number of subsets of set A containing element 3, is

A={1,2,3,4,5,6,7},B={3,4,5}, then the number of subsets C of A such that B-C=phi, is
