Probability Test Review (23-24)

Front

What is the probability of an event?

Back

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

Front

How do you calculate the probability of a specific outcome?

Back

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

Front

What is a sample space in probability?

Back

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

Front

Define independent events in probability.

Back

Independent events are two or more events where the occurrence of one does not affect the occurrence of the other.

Front

What is the formula for combinations?

Back

C(n, r) = n! / (r!(n - r)!), where n is the total number of items, and r is the number of items to choose.

Front

What is the difference between permutations and combinations?

Back

Permutations consider the order of selection, while combinations do not.

Front

How do you find the total number of outcomes in a multi-step experiment?

Back

Multiply the number of choices at each step together.

Front

What is conditional probability?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred.

Front

How do you calculate the probability of two independent events occurring together?

Back

P(A and B) = P(A) * P(B) for independent events A and B.

Front

What is the probability of drawing two specific colored candies without replacement?

Back

P(A then B) = (Number of A) / (Total) * (Number of B after A is drawn) / (Total - 1).
