Probability Review Bronzini

Hannah designs and conducts a computer simulation with 20 trials and uses the data to create the relative frequency bar graph shown. The graph shows the relative frequency of the number of rolls needed in order to roll all of the different numbers on a number cube. According to the results of the simulation, what is the experimental probability that 9 or more rolls are needed to roll all of the different numbers? Express your answer as a percent.
