Question

Mathew performed an experiment in which he spins a spinner. The spinner is divided into five equal parts with a different color oneach part. The results of his experiment are shown below.ColorNumber of Times Landedred11blue1922greenyellow14purple33Based on the experiment above, predict the number of times the arrow will stop on the yellow part of the spinner if he performsthe experiment a total of 198 times.

Answer 1

Case: Spinner probability

Given: A table of values showing the number of times to obtain different values.

Required: To predict the number of times the arrow will stop on the yellow part of the spinner if he performs the experiment a total of 198 times.

Method:

First we understand the number of times each colour appear.

red= 11

blue= 19

green= 22

yellow= 14

purple= 33

Total observtion = 99

A) To predict the number of times the arrow will stop on the yellow part of the spinner if he performs the experiment a total of 198 times will be:

`\begin{gathered} Pr(Y)\text{ }*198 \\ (14)/(99)*198 \\ 14\text{ }*2 \\ 28 \end{gathered}`

Final answer:

The number of time yellow is predicted to appear is 28
