Skill Practice #2

Are the following statements true or false if A = {2, 4, 6, 8, 10}B = {1, 3, 5}1. A = ∅2. 6 ∈A3. n(B) = 54. n(A∩B) = 0See the answers in the bottom right corner.

Sets

List the elements of the following sets:1. Set F is the set of all factors of 12.2. Set S is the set of all states in Australia.3. Set P is the set of the first five prime numbers.See the answers in the bottom right corner.

A set is a collection of objects or things. The objects or things in a set are called elements or members of the set.Consider the colour of the Australian flag(shown below). We can write these colours in a set:C = { blue, red, white}

Let set A be the set of the first square numbers. i.e. A={1, 4, 9, 16}The following statements are true:8 ∈ A reads "8 is an element of set A."n(A)=4 reads "the number of elements in A is 4." or "Set A has four elements."5 ∉ A reads "5 is not an element of set A."
