What is Probability?

Back

Probability is the measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is Theoretical Probability?

Back

Theoretical Probability is the probability calculated based on the possible outcomes in a perfect scenario, without any experimental data.

Front

What is Empirical Probability?

Back

Empirical Probability is the probability determined through experimentation or observation, based on actual outcomes.

Front

What is Subjective Probability?

Back

Subjective Probability is the probability based on personal judgment, intuition, or opinion rather than on exact calculations.

Back

0.58

Front

How do you calculate the probability of an event?

Back

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

Front

What is the range of probability values?

Back

Probability values range from 0 (impossible event) to 1 (certain event).

Front

What does a probability of 1 indicate?

Back

A probability of 1 indicates that the event is certain to occur.

Front

What does a probability of 0 indicate?

Back

A probability of 0 indicates that the event is impossible and will not occur.
