10. Let's take a set of roll numbers of students of a class as a universal set U and
the following are its subsets.
=
{roll numbers which are odd numbers and less than 5}
B={roll numbers which are square numbers between 5 and 10}
C= {roll numbers which are cube numbers between 5 and
30}
D= {roll numbers which are prime numbers between 13
and
17}
a) List the members of the sets A, B, C and D separately.
b) Write the possible subsets of A and D.
c) What are the possible proper subsets of B?
d) What are the possible improper subset of C?
