Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1.

Front

What is theoretical probability?

Back

Theoretical probability is the probability of an event based on the possible outcomes in a perfect scenario. It is what should happen.

Front

What is experimental probability?

Back

Experimental probability is the probability of an event based on the actual results of an experiment or trial.

Front

How do you calculate the probability of an event?

Back

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

Front

Front

What does it mean if an event is 'certain'?

Back

An event is certain if it is guaranteed to happen, with a probability of 1.

Front

What does it mean if an event is 'impossible'?

Back

An event is impossible if it cannot happen at all, with a probability of 0.
