(a) 31

(b) 32

Step-by-step explanation:

We will do (b) first since it will help us do (a).

(b)

There are n(A)=5 elements in . Using the formula for the number of subsets of a given (finite) set, the number of subsets of is

$2^{n(A)}=2^5=32$

(a)

A subset of is called proper if it does not equal . The only subset of that is not proper is itself, so simply subtract 1 from the number of subsets to get the number of proper subsets, which is

32-1=31
