Understanding Probability and Likelihood

The video tutorial provides a quick review of probability and likelihood. It explains the probability of landing on a specific color using a spinner example, converting fractions to percentages, and introduces the likelihood scale. The likelihood scale ranges from 0% (impossible) to 100% (certain), with examples illustrating how to determine the likelihood of events. The tutorial emphasizes understanding the difference between probability and likelihood, using practical examples to clarify these concepts.

What is the probability of landing on a yellow section if there is one yellow section out of five total sections?

• 0.1

• 0.2

• 0.3

• 0.4

How do you convert a probability of 0.2 into a percentage?

• Multiply by 5

• Move the decimal one place to the right

• Move the decimal two places to the right

• Multiply by 10

What does a likelihood of 100% indicate?

• Impossible

• Unlikely

• As likely as not

• Certain

If an event has a 0% likelihood, what does it mean?

• Certain

• Unlikely

• Impossible

• Likely

What is the likelihood of an event that is as likely as not to happen?

• 0%

• 25%

• 50%

• 75%

Which range of likelihood indicates an event is unlikely to happen?

• 25% to 75%

• 0% to 25%

• 50% to 100%

• 0% to 50%

If an event is more than 50% likely but less than 100%, how is it described?

• Unlikely

• Certain

• Likely

• Impossible

What is the likelihood of landing on a non-yellow section if the probability of landing on yellow is 0.2?

• 0.3

• 0.5

• 0.1

• 0.8

What does it mean if an event is described as 'as likely as not'?

• It is certain to happen

• It is impossible to happen

• It is unlikely to happen

• It has an even chance of happening

In the context of the spinner example, what is the likelihood of landing on a section that is not yellow?

• Likely

• Certain

• Unlikely

• Impossible
