1

What is a sample space?

The sample space of an experiment is the set (aka list) of all possible outcomes of that experiment.

 

  • For example, the sample space for flipping one coin is {heads, tails}.
  • The sample space for rolling one die is {1,2,3,4,5,6}

2

What does outcome mean?

A single, specific possible result of an experiment.

3

What does it mean (in regular English words) if the probability of an event is 0?

It means there is absolutely no possibility that the event will happen.

4

What does it mean (in regular English words) if the probability of an event is 1?

It means the event with definitely for sure happen 100 percent of the time.

5

Can a probability ever be greater than 1?

NOOOOOOOOO.

 

The maximum likelihood that something happens is 100% (aka "1").

6

How do you find the probability of a single event?

7

What are three types of probability diagrams that can help us illustrate probability?

  • Venn diagram
  • 2-D grid 
  • Tree chart

8

What is the word for this symbol?

 

 

intersection

9

What is the word for this symbol?

 

 

union

10

If you see the word "given", what type of probability is it?

Conditional probability.

P(A|B)

"Find probability of A given B"

or

"Given B, find probability of A".

11

What is the formula for conditional probability?

12

Challenge Card

 

What is the formula for P(A U B)?

 

(Hint: we usually use this for Venn diagrams)

13

What is the formula to prove that two events are independent?
