SOLUTION:

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
