A computer program ran a simulation of drawing a token out of a bag containing 3 equal categories of tokens labeled Gold, Silver, and Bronze for 300 total trials. After each draw, the token was replaced back into the bag. The results of the simulation are shown in the table below. Compare the experimental probability of drawing a Gold token to its theoretical probability.
The experimental probability is 31/100, which is less than the theoretical probability of 1/3.
