Define a set of positive integers to be balanced if the set is non-empty and the number of even integers in the set is equal to the number of odd integers in the set. How many stric(t)/(p)roper subsets of {1,2,3,4,5,6,7,8,9,10} are balanced?
Why do you classify the question as stupid ?
I can tell you why: The OP is lazy, arrogant, self-assuming, and mentally r*tarded, and is salty that their "correct" answer is wrong.
