if the graph shows that the relative frequency of achieving the goal in four spins is 0.3, this means that in 30% of the 20 trials, the goal was achieved in four spins. Similarly, if the relative frequency of achieving the goal in six spins is 0.4, this means that in 40% of the trials, the goal was achieved in six spins. By comparing these values, we can see that achieving the goal in four spins is less likely than achieving it in six spins, based on the results of Belinda's simulation.
