Basic Theoretical Probability

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of outcomes.

Front

How do you calculate the theoretical probability of an event?

Back

Theoretical probability = (Number of favorable outcomes) / (Total number of outcomes).

If an event is absolutely impossible, what is its probability?

Back

The probability is 0%.

What does it mean if an event is equally likely?

Back

It means that the event has the same chance of occurring as it does not occurring.
