(b) From Salma's results, compute the experimental probability of landing on black. (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.
