Sets

Collections of well defined and distinct objects. It is considered as an object in its own right. One of the most fundamental concepts in Mathematics. Gathering together into a whole of definite, distinct objects of our perception. Sets can be anything: numbers, people, letters of the alphabet, other sets, and so on.

Answers:

Set A is the set of numbers divisible by 5.

Set B is the set of even numbers which are divisible by 2.

A U B = {5, 8, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70}

A ∩ B = {10, 20, 30}

A = 7, B = 8, A U B = 12

Solutions:

1. Set A = {5, 10, 15, 20, 25, 30, 35}

2. Set B = {8, 10, 20, 30, 40, 50, 60, 70}

3. A U B = Set A = {5, 10, 15, 20, 25, 30, 35} + Set B = {8, 10, 20, 30, 40, 50, 60, 70}

A U B = {5, 8, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70}

4. A ∩ B = Set A = {5, 10, 15, 20, 25, 30, 35} compared to Set B = {8, 10, 20, 30, 40, 50, 60, 70}

Common Elements are {10, 20, 30}

A ∩ B = {10, 20, 30}

5. To find the cardinality, simply count the elements of each sets.

Set A = {5, 10, 15, 20, 25, 30, 35} = 7

Set B = {8, 10, 20, 30, 40, 50, 60, 70} = 7

A U B = {5, 8, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70} = 12
