Experimental and Theoretical Probability

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes, calculated using the formula: P(Event) = Number of favorable outcomes / Total number of outcomes.

What is the formula for calculating the probability of an event not occurring?

Back

P(Not A) = 1 - P(A), where P(A) is the probability of the event occurring.

What is experimental probability?

Back

Experimental probability is the likelihood of an event based on actual experiments or trials, calculated as: P(Event) = Number of times the event occurs / Total number of trials.
