Question

A kindergarten teacher asked the students’ parents to send their child to school with two fruits (apples and/or oranges). Below are the combinations of fruits brought to class the next day.

Fruit Number of Students
2 Apples 8
1 Apple and 1 Orange 4
2 Oranges 7
What is the frequency of oranges in the classroom?

Answer 1

The frequency of oranges is the classroom is 47.37%.

Explanation:

The relative frequency of oranges is the number of oranges divided by the total number of fruits.

We have that:

8 students brought 2 apples each. So there are 8*2 = 16 apples

4 students brought an apple and an orange each. So there are 16 + 4*1 = 20 apples and 4*1 = 4 oranges.

7 students brough 2 oranges each. So there are 4 + 2*7 = 18 oranges.

There are 18 oranges, and 20+18 = 38 fruits in total.

So the frequency of oranges in the classrom is

`F = (18)/(38) = 0.4737`
