Sample Space Introduction

The set of all possible outcomes of an experiment.

• Sample Space

• An outcome

• Equally Likely

You flip a coin and it lands on Heads. Heads is a(n):

• Sample Space

• An outcome

You flip a coin and it lands on Tails. Tails is a(n):

• Sample Space

• An outcome

You flip a coin. The sample space is:

• {Heads}

• {Tails}

• {Heads, Tails}

How many possible outcomes are on this spinner?

What is the sample space for this spinner?

• 1

• {8}

• {1, 2, 3, 4, 5, 6, 7, 8}

• 50/50

Is each outcome equally likely?

• Yes, because 8 divided by 2 is 4.

• Yes, because each outcome is the same size, 1/8, of the spinner.

• No, there is not an equal chance of landing on each number.

• No, nothing in life is equally likely.

What is the sample space for this spinner?

• 1, 1, 1, 1, 2, 3, 4, 4

• {1, 2, 3, 4, 5, 6, 7, 8}

• {1, 2, 3, 4}

• 8

There are 8 total outcomes. What is the probability of landing on a 1 ?

• 4/8 or 1/2

• 1

• 4

• 1/8

What is sample space?

• a process with an uncertain result

• a possible result of an action

• a list of all possible outcomes of an event

• a single outcome or group of outcomes
