Question

Rick asked a random sample of 160 students from his school what they did for lunch. The table shows the results of Rick’s survey. Work out the relative frequency of eating school lunch. Input note: give your answer as a fraction.

Answer 1

43/160

Explanation:

To find the relative frequency,

We just have to know things:

1. The data for asked event

2. Total number of data.

With these 2 points, we can create a fraction that is formed like this:

Data of event / Total data

In this case it is:

43/160

Hope this helps
