Question

Observe the Venn diagram and write the given sets U, A, B, A∪B and A∩B.

Answer 1

U = {1,2,3,4,5,6,8,9,10,11,13}
A = {1,2,3,5,7}
B = {1,5,8,9,10}
AUB ( A union B ) = {1,2,3,5,7,8,9,10}
A intersection B = {1,5}

Answer 2

Answer:

U = {2, 3, 7, 1, 5, 10, 9, 8, 4, 11, 13}

A = {2, 3, 1, 7, 5}

B = {1, 5, 10, 9, 8}

A∪B = {1, 2, 3, 7, 5, 8, 9, 10}

A∩B = {1, 5}

Step-by-step explanation:

In the given Venn diagrams,

We have been provided a Universal set, U and two sets A and B.

So,

Universal Set, U is given by,

U = {2, 3, 7, 1, 5, 10, 9, 8, 4, 11, 13}

It means all the values we an see are the part of the Universal set.

Set A, is given by,

A = {2, 3, 1, 7, 5}

It consists of all the values inside of set A.

Set B, is given by,

B = {1, 5, 10, 9, 8}

it consists of all the values inside of set B.

Set A∪B, is given by,

A∪B = A + B = {1, 2, 3, 7, 5, 8, 9, 10}

It consists of all the values of the set A and B altogether.

Set A∩B, is given by,

A∩B = {1, 5}

It consists of the values common to the sets A and B.
