Types of Sets

WHAT TYPE OF SET AM I?

{2, 4, 6 , 8, 10...}

• A set of even numbers

• A set of odd numbers

• A set of prime numbers

• A set containing the multiples of 3

A set which contains a single element is called a (a)   set.

WHAT TYPE OF SET AM I?

{trees with legs}

• Finite set

• Null set

• Infinite set

• Equal set

What element/s is shared between the two sets?

A={3, 5, 7, 9, 14} and B={2, 4, 5, 9, 10}

• {3, 5}

• {5}

• {3, 4, 7, 10}

• {5, 9}

List the elements of this set

A={All the factors of 16}

• {1, 2, 4, 8, 16}

• {1, 16}

• {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}

• {}

The two sets A and B are said to be (a)   if they have exactly the same elements, the order of elements do not matter.

The two sets A and B are said to be (a)   if the set does not contain any common element.

Which of the following two sets are equal?

• A = {1, 2} and B = {1}

• A = {1, 2} and B = {1, 2, 3}

• A = {1, 2, 3} and B = {2, 1, 3}

• A = {1, 2, 4} and B = {1, 2, 3}

Write X = {1, 4, 9, 16, 25,…} in set builder form.

• X = {x: x is a set of prime numbers}

• X = {x: x is a set of whole numbers}

• X = {x: x is a set of natural numbers}

• X = {x: x is a set of square numbers}
