Fill in the table below. Round your answers to the nearest thousandth.
(a)
Assuming that the machine is fair, compute the theoretical probability of getting an odd number.
(b)
From these results, compute the experimental probability of getting an odd number.
(c)
Assuming that the machine is fair, choose the statement below that is true:
With a large number of trials, there must be no difference between the experimental and theoretical probabilities.
With a large number of trials, there might be a difference between the experimental and theoretical probabilities, but the difference should be small.
With a large number of trials, there must be a large difference between the experimental and theoretical probabilities.
