What is the probability of a compound event?

Back

The probability of a compound event is the likelihood of two or more events happening together, calculated by multiplying the probabilities of the individual events if they are independent.

What is the formula for calculating the probability of two independent events A and B occurring together?

Back

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

How do you calculate the probability of drawing a blue marble and flipping heads?

Back

Multiply the probability of each event: P(blue marble) * P(heads) = (2/9) * (1/2) = 1/9.

What is a tree diagram in probability?

Back

A tree diagram is a visual representation of all possible outcomes of an event, showing the paths that can be taken.

If a die is rolled and a coin is flipped, how many total outcomes are there?

Back

12 total outcomes (6 outcomes from the die and 2 from the coin: 6 * 2 = 12).

What is the probability of rolling a 3 and spinning a red?

Back

1/24, calculated as P(rolling a 3) * P(spinning red) = (1/6) * (1/4).
