Hello students, let us discuss the solution of this question.
00:04
Here, a multi -set is given which is equal to a, which is equal to small a, small b, small b and c.
00:14
This is a multi -set containing two a's, two bs and one c.
00:19
We have to find three combinations of multi -set a, such that the first one should contain two a's, the other one should contain two bs and the third one should contain one c.
00:34
So let us discuss the solution of this question.
00:41
Let me tell you what is a multi -set.
00:43
A multi -set is a collection of unordered elements where any element can occur finite number of time.
00:49
Therefore a is a multi -set because it contains every element which occurs finite number of times.
00:56
So let us discuss the solution.

The first one is a cap which is equal to we have to add 2 a's so a...
