(a) From Amanda's results, compute the experimental
probability of landing on blue or red.
0
(b) Assuming that the spinner is fair, compute the
theoretical probability of landing on blue or red.
0
(c) Assuming that the spinner is fair, choose the
statement below that is true.
The experimental and theoretical probabilities
must always be equal.
As the number of spins increases, we expect the
experimental and theoretical probabilities to
become closer, though they might not be equal.
As the number of spins increases, we expect the
experimental and theoretical probabilities to
become farther apart.
