Tammy rolled a number cube 25 times and got the following results. Outcome Rolled 1 2 3 4 5 6 Number of Rolls 3 6 4 5 2 5 Answer the following. Round your answers to the nearest thousandths. (a) From Tammy's results, compute the experimental probability of rolling an even number. (b) Assuming that the cube is fair, compute the theoretical probability of rolling an even number. (c) Assuming that the cube is fair, choose the statement below that is true. As the number of rolls 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 rolls increases, we expect the experimental and theoretical probabilities to become farther apart.

Step 1
So, the experimental probability of rolling an even number is: (6 + 5 + 5) / 25 = 0.64 Show more…

Teresa rolled a number cube 1000 times and got the following results. Outcome Rolled 1 2 3 4 5 6 Number of Rolls 182 157 167 159 172 163 Fill in the table below. Round your answers to the nearest thousandths. (a) From Teresa's results, compute the experimental probability of rolling a 3 or 5. (b) Assuming that the cube is fair, compute the theoretical probability of rolling a 3 or 5. (c) Assuming that the cube is fair, choose the statement below that is true: With a large number of rolls, there might be a difference between the experimental and theoretical probabilities, but the difference should be small. With a large number of rolls, there must be a large difference between the experimental and theoretical probabilities. With a large number of rolls, there must be no difference between the experimental and theoretical probabilities.
