What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on all possible outcomes, calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.

How do you calculate the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of possible outcomes).

Back

It means that the event has a greater chance of occurring than not occurring.
