Compound Probability Practice

Front

What is compound probability?

Back

Compound probability refers to the probability of two or more events happening at the same time. It can be calculated using the multiplication rule for independent events or the addition rule for mutually exclusive events.

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

Back

To calculate the probability of two independent events A and B occurring, multiply their individual probabilities: P(A and B) = P(A) * P(B).

What is the probability of drawing a specific card from a standard deck of 52 cards?

Back

The probability of drawing a specific card (e.g., the Ace of Diamonds) is 1/52, since there is one desired outcome out of 52 possible outcomes.

Front

What is the probability of drawing a card that is either a heart or a spade from a standard deck?

Back

There are 13 hearts and 13 spades in a deck, so the probability is P(heart or spade) = (13 + 13) / 52 = 26/52 = 1/2.

Front

What is the formula for calculating the probability of an event?

Back

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

What is the probability of getting tails when flipping a coin?

Back

The probability of getting tails when flipping a fair coin is 1/2, since there are two equally likely outcomes: heads or tails.

Front

How do you find the probability of two events occurring in sequence without replacement?

Back

To find the probability of two events occurring in sequence without replacement, multiply the probability of the first event by the probability of the second event given that the first event has occurred.

Front

What is the probability of rolling a 3 on a standard number cube?

Back

The probability of rolling a 3 on a standard number cube (1-6) is 1/6, since there is one favorable outcome out of six possible outcomes.

Front

What is the probability of getting a perfect square when spinning a spinner numbered 1-4?

Back

The perfect squares in this range are 1 and 4. The probability is P(perfect square) = 2/4 = 1/2.

Front

What is the probability of drawing a red card from a standard deck of cards?

Back

There are 26 red cards (hearts and diamonds) in a deck of 52 cards, so the probability is P(red card) = 26/52 = 1/2.
