Representing Sample Space

4/13/21

• Sample Space: is the set of all possible outcomes.

• Three ways to represent a sample space are: to list the possible outcomes, to create a tree diagram, or to create a Venn diagram.

• Event is any combination of outcomes. Upper case letters like A and B represent events.

• P(A) = 0 means the event A can never happen. 

• P(A) = 1 means the event A always happens. 

• P(A) = 0.5 means the event A is equally likely to occur or not to occur.

​Probability - the chance that something will occur.
