i am new carrier360 pls help me...........
let A and B has 2 and 4 elements. then no of subsets of A*B having 3 or more elements---
Total number of elements in A x B = 8
Total number of subsets of A x B = = 256
Number of subsets having 3 or more elements = 256 - ( no. of subsets having (1 element + 2 elements + 0 elements))
= 256 - (1 null set + 8C2 having two elements + 8C1 having one element)
= 256- (1+28+8) = 219
