Intro to Probability likelihood 2 --2025

What is Probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, where 0 means the event will not happen and 1 means it will definitely happen.

Front

What is a Sample Space?

Back

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

Front

What is an Event in Probability?

Back

An event is a specific outcome or a set of outcomes from a probability experiment.

Front

What does it mean if an event is Certain?

Back

A certain event is an event that is guaranteed to happen, with a probability of 1.

Front

What does it mean if an event is Impossible?

Back

An impossible event is an event that cannot happen, with a probability of 0.

Front

How do you calculate the Probability of an Event?

Back

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is a Favorable Outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event we are interested in.

Front

What is the difference between Independent and Dependent Events?

Back

Independent events are events where the outcome of one does not affect the outcome of the other. Dependent events are events where the outcome of one event affects the outcome of another.

Front

What is a Compound Event?

Back

A compound event is an event that consists of two or more simple events.

Front

What is the Law of Large Numbers?

Back

The Law of Large Numbers states that as the number of trials increases, the experimental probability of an event will get closer to the theoretical probability.
