I have d now this question about 8 times and STILL can't seem to figure it out. Please help :(
The spinner below shows 5 equally sized slices. Kira spun the dial 25 times and got the following results.
Outcome White Grey Black
Number of Spins 18 1 6
Fill in the table below. Round your answers to the nearest thousandths.
(a) From Kira's results, compute the experimental probability of landing on grey. 0.050
(b) Assuming that the spinner is fair, compute the theoretical probability of landing on grey. 0.200
(c) Assuming that the spinner is fair, choose the statement below that is true:
- As the number of spins increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal.
- The experimental and theoretical probabilities must always be equal.
-As the number of spins increases, we expect the experimental and theoretical probabilities to become farther apart.
