Question

If x represents number of subsets of A 2,3,4,5}, and y represents number of subsets of B = {a,b} then express x interms of y

Answer 1

(x,y,z). B=(a,b,c,d). Total no. Of subsets = 2 ^8. Subsets having 1 element are 8. Subsets ... the total number of elements plrec=sen tin AxB will be equal to n(A)*n(B)=4*2=8 ...
