Question

Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits, and Elderberry. To make a decision, they use a spinner divided into four colors. They spin it 60 times to check the fairness of their model and record the results in this table.

The relative frequency of the spinner landing on green is


The relative frequency of the spinner landing on blue is


The relative frequency of the spinner landing on yellow is


The relative frequency of the spinner landing on red is

Answer 1

Explanation:

The theoretical frequency would be 1/4, and if spun 60 times, 15/60.

The relative frequency is how many times it actually landed on each color.

So green is 6/60

Blue is 24/60

Yellow is 9/60

Red is 21/60

I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:

Green: 1/10

Blue: 4/10

Yellow: 3/20

Red: 7/20
