How does the experimental probability compare to the theoretical probability for each possible situation?

• The experimental probability is always equal to the theoretical probability.

• The experimental probability is always greater than the theoretical probability.

• The experimental probability is always less than the theoretical probability.

• The experimental probability may vary and not always match the theoretical probability.

A bag contains the letters shown. You randomly draw a tile, record it, and then return it to the bag. The bar graph shows the results of drawing a letter 50 times. Compare the theoretical and experimental probabilities of the event. What is the probability of drawing an S?
