Answer 1

4 and 6.here it is the answer

Answer 2

We know that if a set contains n elements, then the subsets of the sets is 2^n.

Total number of all possible subsets = 2^5 = 32.

Now,

Given set A = {2,4,6,8,10}.

⇒ Subset of A containing no elements = { }

⇒ Subset of A containing one element each = {2},{4},{6},{8},{10}

⇒ Subset of A containing two elements each = {2,4}, {2,6}, {2,8}, {2,10}, {4,6},{4,8},{4,10},{6,8},{6,10},{8,10}.

Hope this helps!
