Conduct the experiment to get the experimental probability. Jason L. Theoretical and experimental probabilities ... Unit test. A probability is a number that tells you how likely (probable) something is to happen. I'll call this value (for each row) the incremental probability (of "landing" there). ____ 1. Example: According to theoretical probability, how many times can we expect to land on each color in a spinner, if we take 16 spins? You can calculate experimental probability by running an experiment and looking at the actual results.
