What is probability?

Back

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

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.

What is the probability of landing on a specific area of a shape?

Back

To find the probability of landing on a specific area of a shape, divide the area of the desired section by the total area of the shape.

What is the formula for the probability of independent events occurring?

Back

For independent events A and B, the probability of both A and B occurring is P(A) * P(B).

What is the probability of at least one event occurring?

Back

The probability of at least one event occurring can be found using the formula: P(A or B) = P(A) + P(B) - P(A and B).

What is the concept of complementary events in probability?

Back

Complementary events are two outcomes of an event that are mutually exclusive and exhaustive, meaning one must occur if the other does not. The probability of an event and its complement always adds up to 1.

How do you calculate the probability of multiple events happening in sequence?

Back

To calculate the probability of multiple events happening in sequence, multiply the probabilities of each individual event if they are independent.

Front

What is the difference between dependent and independent events?

Back

Independent events are those whose outcomes do not affect each other, while dependent events are those where the outcome of one event affects the outcome of another.

What is a probability distribution?

Back

A probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment.
