Theoretical probability is displayed in the opening screen. The green line shows the theoretical probability for each event.

Experiment probability:  Clicking the "?" button starts a probability experiment. The experimental probability will likely approach the theoretical probability for a large sample. Click the "Reset" button if you wish to complete additional experimental probability trials
