Exploring Compound Probability Concepts

Mr. Kaul introduces compound probability, explaining how it involves multiple events occurring together. He discusses the concept of sample space, which is the set of all possible outcomes, and demonstrates how to calculate it by multiplying the outcomes of individual events. The video covers three methods to visualize and solve compound probability problems: tree diagrams, tables, and organized lists. Tree diagrams are recommended for more than two events, tables for two events, and organized lists for straightforward problems. Examples include choosing ice cream combinations and rolling dice with spinners.

What is compound probability concerned with?

• Predicting future events without data

• Compound events involving more than one action

• Single events only

• Events based on historical data

How do you find the total number of possibilities in a compound event?

• By adding the number of outcomes for each event

• By multiplying the outcomes of each event

• By dividing the outcomes of one event by the other

• By subtracting the outcomes of one event from the other

When is a tree diagram especially recommended?

• For calculating simple probabilities

• When dealing with single events

• For events with only two outcomes

• When there are more than two events

What is the probability of choosing chocolate ice cream with cherries?

• 1/4

• 2/12

• 1/6

• 1/12

How many total combinations are possible with two ice creams, two sauces, and three toppings?

• 24

• 6

• 8

• 12

What does a table help organize in compound probability?

• Events with more than two variables

• Single events only

• Compound events with two variables

• Predictions without actual data

What is the probability of rolling a 4 and landing on red with a spinner?

• 1/6

• 1/8

• 1/12

• 1/24

What is the simplified probability of getting an odd number and red on a spinner and dice roll?

• 1/24

• 1/12

• 1/8

• 1/6

What is the probability of getting at least one head when flipping a coin twice?

• 3/4

• 1

• 1/2

• 1/4

How many possibilities exist when flipping a coin twice?

• 2

• 8

• 6

• 4
