PRACTICE Find Probabilities of Compound and Simple Events

Define 'compound event' in probability.

• A compound event is an event that consists of two or more simple events.

• A compound event is an event that occurs only once in a probability experiment.

• A compound event is an event that cannot be broken down into simpler events.

• A compound event is an event that has a probability of zero.

How do you calculate the probability of a compound event?

• By adding the probabilities of the individual events

• By multiplying the probabilities of the individual events if they are independent

• By taking the average of the probabilities of the individual events

• By subtracting the probabilities of the individual events from one

What is the difference between independent and dependent events?

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

• Dependent events are events that occur at the same time.

• Independent events are always more likely to happen than dependent events.

• Dependent events are events where the outcome of one does not affect the outcome of another.

How do you express probability as a percentage?

• Add 50 to the probability

• Multiply the probability by 100

• Divide the probability by 100

• Subtract the probability from 100

What is the probability of a simple event?

• The probability of a simple event is the ratio of the number of favorable outcomes to the total number of possible outcomes.

• The probability of a simple event is always 1.

• The probability of a simple event is the number of possible outcomes divided by the number of favorable outcomes.

• The probability of a simple event is the sum of all possible outcomes.

What is the probability of flipping a coin and getting heads?

• P(Heads) = 1 / 2

• P(Heads) = 1 / 3

• P(Heads) = 2 / 3

• P(Heads) = 3 / 4

What is the probability of winning a prize if there are 10 prizes and 2 are won?

• 1/2

• 1/5

• 1/10

• 2/5

If a fair coin is flipped, what are the possible outcomes?

• Heads and Tails
