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.

What is experimental probability?

Back

Experimental probability is the likelihood of an event based on actual experiments or trials, calculated as the number of times the event occurs divided by the total number of trials.
