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:
[tex]\begin{gathered} Pr(Y)\text{ }\times198 \\ \frac{14}{99}\times198 \\ 14\text{ }\times2 \\ 28 \end{gathered}[/tex]Final answer:
The number of time yellow is predicted to appear is 28
