Question

How do you do solve this?

Answer 1

The relative frequency is the frequency of the item divided by the total number of all items. The total number of all items here is: 50 + 40 + 90 +20 = 200.


`Burgers = (50)/(200) = 25%`

`Pasta = (40)/(200) = 20%`

`Pizza = (90)/(200) = 45%`

`Salad = (20)/(200) = 10%`

Hope this helps!
