Aspinner has five equal parts labeled from 1 to 5. the spinner is spun twice. what is the probability of getting a 4 twice in a row?

Step-by-step explanation:

Given : A spinner has five equal parts labeled from 1 to 5.

           The spinner is spun twice.

To Find: What is the probability of getting a 4 twice in a row?

Solution:

Numbers on spinner = {1,2,3,4,5}=5

Favorable outcome = {4}=1

So, probability of getting 4 on first spin =

Now probability of getting 4 on second spin =

So,  the probability of getting a 4 twice in a row =

                                                                               =  

Hence the probability of getting a 4 twice in a row is    

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
