how many possible subsets are there in set b {1,3,5,7,9}

Answer: # of subsets = 2^5 = 32
----------------------------------
Pattern: {_,_,_,_,_}
Each position either does or does not have the corresponding number.
Example: {_,_,5,_,9} is one of the subsets.
So there are 2^5 = 32 different patterns, or subsets.
