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.
A graph titled proportion of threes has frequency on the x-axis, and probability on the y-axis. The graph increases, and then stays steady around y = 0.17.
Which conclusion can be drawn from this graph?
There is a 20% chance of rolling a 3 with this die.
The long-run frequency of rolling a 3 appears to be about 0.17.
Because the probabilities on the left part of the graph fluctuate so much, we cannot conclude that this is a fair number cube.
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.
