Question

Select the correct answer from each drop-down menu.David, Matt, and Taylor pick a billiard ball from a bag of red, blue, and yellow balls. They pick a ball and replace it 75 times. They record their results in this table.

Answer 1

The relative frequency of picking a red ball: 24/75 = 0.32

The relative frequency of picking a blue ball: 27/75 = 0.36

The relative frequency of picking a yellow ball: 24/75 = 0.32

To find the relative frequency we divide the frequency buy the total number of balls. This total number remains the same because the balls are replaced each time.

The model is a mathematical representation of the situation.

To test whether or not the experiment is fair, we can compare the expected frequency to the actual frequency. If there are the same number of red, blue and yellow balls then they each should be picked a thr
