Exploring Compound Probability Concepts

What is a compound event in probability?

• Two or more simple events happening together

• An event with a guaranteed outcome

• The set of all possible outcomes

• A single outcome from an experiment

What does the sample space represent in probability?

• The probability of an event occurring

• The total number of successful outcomes

• A single possible outcome of an experiment

• The set of all possible outcomes of an experiment

What is the probability of an event that cannot happen?

• It's undefined

• 0

• 1/2

• 1

Which of the following is a simple event?

• Spinning a spinner and landing on blue or red

• Drawing a card from a deck and getting a red card

• Flipping a coin and getting heads

• Rolling a die and getting an even number

How can the probability of landing on dark gray and rolling a five be calculated?

• By adding the probabilities of each event

• By dividing the outcomes of one event by the other

• By multiplying the probabilities of each event

• By subtracting one event's probability from the other

How many total outcomes are there when spinning the spinner and rolling the dice in the example?

• 12

• 6

• 36

• 24

What is the probability of rolling a four and a five with two dice?

• 2/36

• 1/36

• 5/36

• 1/18

What is the probability of rolling a four or a five with two dice?

• 5/36

• 10/36

• 25/36

• 20/36

What is the probability of spinning an odd number and rolling an even number?

• 3/10

• 9/30

• 1/2

• 1/5

What strategy is suggested for finding the probability of compound events?

• Using lists and tables to organize outcomes

• Guessing based on past experiences

• Only focusing on successful outcomes

• Ignoring the sample space
