Probability of Drawing Outcomes

The video tutorial explains how to find the sample space in a two-step experiment and use it to calculate probabilities. It introduces tree diagrams as a tool for visualizing probabilities, especially when outcomes are not equally likely. The tutorial provides examples of calculating probabilities using both sample spaces and tree diagrams, highlighting the differences in approach when dealing with unequal probabilities.

What is the probability of getting a 'blue then red' combination if there are 8 possible outcomes?

• 1/8

• 1/16

• 1/4

• 1/2

In a tree diagram with equally likely outcomes, what is the probability of each outcome if there are 4 possible colors?

• 1/5

• 1/4

• 1/3

• 1/2

How do you calculate the probability of 'red then white' when the outcomes are not equally likely?

• Add the probabilities

• Multiply the probabilities

• Divide the probabilities

• Subtract the probabilities

In a two-step experiment with 3 red and 2 white pieces, what is the probability of drawing 'red then white'?

• 3/25

• 4/25

• 5/25

• 6/25

What is the probability of drawing 'white then white' from a set of 4 red, 3 white, and 1 purple pieces?

• 7/64

• 8/64

• 9/64

• 6/64
