Answer:
Option B.
Step-by-step explanation:
In the question the number categories on the spinner are not given.
Consider there are 5 different categories on the spinner.
A = Spinner land on "Action".
So, probability of land on "Action" is
[tex]P(A)=\frac{1}{5}[/tex]
Number of spins, n= 60 times
The expected number of land on "Action" is
[tex]\text{Expected value}=n\times P(A)[/tex]
[tex]\text{Expected value}=60\times \frac{1}{5}[/tex]
[tex]\text{Expected value}=12[/tex]
Therefore, the correct option is B.
Answer:
c) 15
Step-by-step explanation:
If there are 6 genre on the spinner, that represents the total possible outcomes, and Action is only one of them, so its probability in one try is
[tex]P_{action} =\frac{1}{4}[/tex]
Then, he tried 60 times, that means we have to multiply the simple probability to the total number of trials.
[tex]E=60 \times \frac{1}{4}= 15[/tex]
He should expect to land on Action 15 times out of 60.
Therefore, the right answer is c) 15.
