ans:- s=3

Answer 2

Answer:

There are 4 subsets for this set, namely the empty set, {1}, {2},{1,2}. In general there are 2^n elements with n being the number of elements in the set. This is because each element has 2 options, either to be in a particular subset or to not and since this is true for all of them you multiple to get the result of 2^n=2^2=4 in this case.
