Sets also can be represented using a graphic organizer called a Venn diagram .

 

 

You can draw a Venn diagram to represent the building bricks shown in the picture below.

Consider the set P of primary coloured building bricks.

 

 

If the set P of primary colors is listed inside the circle, then what is listed on the outside?

In a Venn diagram, the area outside the circle but inside the rectangle lists all the elements that are in the universal set U but not members of set P . This set of elements is called the complement of P . Complement is denoted as P' , which is read as P prime .

 

 

The Venn diagram above can be summarized as follows:

U = the universal set = {all the brick colours shown in the picture}

P = {primary coloured bricks} = {Red, Yellow, Blue}

P' = the complement of P = {bricks that are not primary coloured}

= {Green, Orange, Purple, Pink, Turquoise}
