Discrete Mathematics

For each of the following cases, find examples of three sets A, B, C that make the statement true.

a. A B C

b. A B C

c. A B C

d. A B C

Solution

a> A ={1,2} B={1,2,3} C={1,2,3,4}

As B contains each element of A, A is a subset of B.

As C contains each element of B as well of A, B and A both are subsets of C.

So the relation in a> part holds for the above example
