Fill in the table below. Round your answers to the nearest thousandth.
(a)From Leila's results, compute theexperimental probabilityof rolling a5
or6
.
(b)Assuming that the cube is fair, compute thetheoretical probabilityof rolling a5
or6
.
(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 besmall.
With a large number of rolls, there must benodifference between the experimental and theoretical probabilities.
With a large number of rolls, there must be alargedifference between the experimental and theoretical probabilities.
