Unit 12 probability homework 2 counting outcomes theoretical and experimental probability

Theoretical probability is calculated by taking the number of favorable outcomes over the total number of outcomes. Experimental probability is calculated by taking the actual outcomes over the total number of trials.

Theoretical probability describes how likely an event is to occur. We know that a coin is equally likely to land heads or tails, so the theoretical probability of getting heads is 1/2. Experimental probability describes how frequently an event actually occurred in an experiment.

The experimental probability of rolling a 4 is 0.24, or 24%.

The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.
