Thomas is running an after-school day care center with 8 children. He is thinking about providing tutoring
services for the children and is doing research on their grades in school. Each child takes 3 classes and either
passes or fails each class.
The children's grades are shown in the table below. "P" represents a passed class, and "F" represents a failed
class.
Drag the bars to make a relative frequency plot that shows the proportion for each possible number of classes
failed by a child.

The relative frequency for Pooja, Melissa, Ernesto, and Dalia is 0.33,  for Salma and Olga is 0.66, and for Pedro and Divya is 0.

What is the relative frequency?

The relative frequency describes through a percentage (0% to 100%) or an equivalent, the frequency of an event. Here are some examples:

  • If in a city it rains 15 out of the 30 days, the relative frequency is 50% or 0.5.
  • If a specific soccer team never wins matches, the relative frequency for winning is 0% or 0.

How to calculate relative frequency?

To find relative frequency simply use this formula

  • total of occurrence of a specific event/ total possible events or outcomes.

Let's use this formula to calculate the frequency of classes failed by each child.

  • Pooja - PFP

1/ 3 = 0.33

  • Melissa - PPF

1/3 = 0.3

  • Salma -FFP

2/3 = 0.66

  • Pedro - PPP

0/ 3 = 0

  • Ernesto -PFP

1/3 =0.33

  • Dalia -PPF

1/3 = 0.33

  • Olga -FPF

2/3 = 0.66

  • Divya -PPP

0 /3 = 0

Finally, create the bar graph using the information.
