What is classical probability?

Back

Classical probability is based on the assumption that all outcomes in a sample space are equally likely.

Front

What is empirical probability?

Back

Empirical probability is based on observed data and experiments rather than theoretical calculations.

Front

What is subjective probability?

Back

Subjective probability is based on personal judgment or opinion rather than exact calculations.

Front

What does it mean for an event to be unusual in probability?

Back

An event is considered unusual if its probability is less than or equal to 0.05.

How do you calculate the probability of an event?

Back

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

What is the formula for calculating odds?

Back

Odds = (Probability of the event occurring) / (Probability of the event not occurring).
