Finding the Probability of Compound Events with Tree Diagrams

This video tutorial teaches how to find the probability of compound events using tree diagrams. It begins with an introduction to the concept and explains how to list all possible outcomes using organized lists. The video highlights common mistakes students make when creating these lists and offers a detailed guide on constructing tree diagrams. Finally, it demonstrates how to calculate the probability of specific outcomes using these diagrams.

What is one common mistake students make when creating an organized list of outcomes?

• Forgetting to include all possible outcomes

• Listing the same outcome multiple times

• Using incorrect symbols to represent outcomes

• Not considering the order of events

What is the first step in creating a tree diagram for compound events?

• Showing the routes and choices for the first event

• Calculating the probability of each outcome

• Identifying the desired outcome

• Listing all possible outcomes

In a tree diagram, what do the 'leaves' represent?

• The final outcomes

• The sequence of events

• The initial choices

• The probability of each event

How many possible ways are there to pull a red, green, and blue marble from a bag?

• 6

• 3

• 4

• 5

What is the probability of drawing marbles in the order of green, blue, and red?

• 1/4

• 1/3

• 1/6

• 1/5
