Answer the following. Round your answers to the nearest thousandths.
(a)From Mary's results, compute the experimental probability of landing on red.
(b)Assuming that the spinner is fair, compute the theoretical probability of landing on red.
(c)Assuming that the spinner is fair, choose the statement below that is true.
With a large number of spins, there might be a difference between the experimental and
theoretical probabilities, but the difference should be small.
With a large number of spins, there must be no difference between the experimental and
theoretical probabilities.
With a large number of spins, there must be a large difference between the experimental and
theoretical probabilities.
