Question

The U in the upper right corner stands for the

bigger set
universal set
infinite set
complement

Answer 1

Universal set

Explanation:

We need to find U in the upper right corner stands for what

Option 1 : bigger set

We cannot say this a bigger set without comparing it with another sets and since it is also containing another sets So, it is not said to be a bigger set.

Option 1 is wrong .

Option 2 : Universal Set

Definition of Universal Set : The set which contains all elements or all objects and of which all other sets are subsets.

Since we can see that SET M and SET N are contained in SET U

Thus U is a universal set.

Option 2 is correct .

Option 3: infinite set

we can see in the figure that it is finite set .

So, it is not infinite set.

Option 3 is wrong .

Option 4: complement

it is not a complement set (refer given figure )

Option 4 is wrong .

Answer 2

The U in the upper right corner stands for the universal set.
As universal set defined the set containing all objects or elements and of which all other sets are subsets. So, the answer is B.
