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

Define dependent events in probability.

Back

Dependent events are events where the outcome of one event affects the outcome of another event.

Front

Define independent events in probability.

Back

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

Front

What is the formula for calculating the probability of at least one event occurring?

Back

P(at least one) = 1 - P(none)

Front

How do you calculate the probability of drawing multiple face cards from a deck?

Back

Use the formula: P(face card 1) * P(face card 2 | face card 1) * P(face card 3 | face cards 1 and 2).

Front

What is the total number of cards in a standard deck?

Back

A standard deck has 52 cards.

Front

What is the probability of selecting a female given they like a specific car brand?

Back

This is a conditional probability, calculated as P(Female | Likes Toyota) = P(Female and Likes Toyota) / P(Likes Toyota).

Front

What is the probability of two events A and B occurring together?

Back

P(A and B) = P(A) * P(B | A) for dependent events.

Front

What is the probability of an event not occurring?

Back

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

Front

What is the probability of selecting a face card from a deck?

Back

There are 12 face cards in a deck of 52 cards, so P(face card) = 12/52 = 0.2308.
