Which conclusion can be drawn from this graph? A six-sided number cube is rolled and the proportion
of 3s is calculated. The graph shows the long-run
relative frequency of 100 rolls of this die.
Proportion of 3s
O There is a 20% chance of rolling a 3 with this die.
O The long-run frequency of rolling a 3 appears to be
about 0.17
O Because the probabilities on the left part of the
graph fluctuate so much, we cannot conclude that
this is a fair number cube.
O This number cube must be fair because each
outcome of rolling a 1, 2, 3, 4, 5, or 6 has the same
probability of occurring.
