Equally Likely Outcomes and Sample Space

This video tutorial for grade seven covers module 5 on statistics and probability, focusing on chance experiments with equally likely outcomes. It introduces key terms such as outcome, sample space, and equally likely, using a spinner as an example to explain these concepts. The video demonstrates how to identify sample space and outcomes, and explains when outcomes are equally likely based on the size of spinner sections.

What is the main focus of this lesson?

• Learning about historical events

• Exploring chance experiments with equally likely outcomes

• Understanding algebraic expressions

• Studying chemical reactions

What does the term 'outcome' refer to in an experiment?

• The time taken to complete the experiment

• The tools used in the experiment

• The result of a single observation

• The process of conducting the experiment

What is a 'sample space' in the context of an experiment?

• The time duration of the experiment

• The set of all possible outcomes

• The number of trials in the experiment

• The location where the experiment is conducted

When are outcomes considered 'equally likely'?

• When they occur at different times

• When they have the same probability of occurring

• When they are not possible

• When they are observed in different experiments

In the spinner example, what colors are part of the sample space?

• Red, Yellow, Green

• Red, Blue, Yellow

• Green, Yellow, Blue

• Green, Blue, Red

What was the outcome when the spinner was spun the first time?

• Blue

• Yellow

• Red

• Green

Which two colors on the spinner are equally likely to occur?

• Green and Red

• Blue and Yellow

• Red and Blue

• Green and Yellow

Why are the red and blue sections on the spinner equally likely?

• They are next to each other

• They are the same size

• They are different sizes

• They are different colors

What happens if the spinner is spun multiple times?

• It only lands on red

• It stops working

• It may land on different colors

• It always lands on the same color

What is the significance of equally sized sections on the spinner?

• They ensure different outcomes

• They make the spinner colorful

• They ensure equal likelihood of outcomes

• They make the spinner spin faster
