What is probability?

Back

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

Front

What is the formula for calculating probability?

Back

The probability of an event is calculated as: P(Event) = Number of favorable outcomes / Total number of outcomes.

Front

Define 'favorable outcomes' in probability.

Back

Favorable outcomes are the specific outcomes that satisfy the conditions of the event we are interested in.

Front

What does it mean if the probability of an event is 0?

Back

A probability of 0 means that the event cannot occur.

Front

What does it mean if the probability of an event is 1?

Back

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

Front

How do you calculate the probability of multiple independent events occurring?

Back

For independent events, the probability of both events occurring is the product of their individual probabilities: P(A and B) = P(A) * P(B).

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on the expected outcomes in a perfect world, while experimental probability is based on actual experiments and observations.

Front

How do you find the probability of an event not occurring?

Back

The probability of an event not occurring is calculated as: P(Not A) = 1 - P(A).

Front

What is conditional probability?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred, denoted as P(A|B).
