Answer 1

Step 1:

In this question, we are given the following:

The following table lists the ages and number of players per group that are on a hockey team.

Let A= (hockey players who are 12 years old)

How many players are in the complement of A?

Step 2:

We are meant to find the number of players that are in the complement of A:

Total number of players =

`2+5+9+\text{ 3 = 19}`

Let A= (hockey players who are 12 years old) = 3

Number of players that are in complement of A =

`\text{19 - 3 = 16}`
