A paper cup is dropped and its landing position is recorded. The cup can land on the side, on the open end, or on the closed end. The results of 20 trials are shown in the table below:

A chart shows tally marks. Main title for the chart is Paper Cup Experiment. The title for the second column is Number of times occurred. The tally mark corresponding to open shows a set of 4 vertical lines cut by a slanting line. The tally mark corresponding to closed shows a set of 4 vertical lines cut by a slanting line and a set of 3 vertical lines. The tally mark corresponding to side shows a set of 4 vertical lines cut by a slanting line and a set of 2 vertical lines.
Based on the table, which of the following best compares the experimental probability of the cup landing on its open end with the experimental probability of the cup landing on its closed end? (1 point)

The probabilities are equal.
The probability of landing on the open end is greater.
The probability of landing on the closed end is greater.
No conclusion can be made.
