let p ={aaron, bob, phill, john, chad}
how many subsets contain neither aaron nor bob
the answer is 2^(5-2)= 2^(3)= 8
but another question i saw was a = {1, 2, 3, 4, 5 ,6 ,7}
how many subsets of a include {2, 4, 6}
and the anwser is 2^(7-3)= 2^4=16
why is the method we use for include and niether the same? i doubt there is an error becuase these questions were done by my professor.
