Let A and B be the multisets {3 a, 2 b, 1 c) and {2 a. 3 b. 4 d), respectively. Find

a) A ∪ B.

b) A ∩ B.

c) A – B.

d) B – A.

e) A + B.

Step 1</p>

Given the multisets

and

We need to find the following

Step 2</p>

a)

The union of 2 multisets contains the elements of highest multiplicities from both the sets.

Step 3</p>

b)

The intersection of 2 ,multisets contains the common elements with minimum multiplicity, of both the sets
