Probability
The chance of something happening
Event
Something may happen
Outcome
One of the possible events in a probability situation.
Sampling
An experiment that is conducted to predict probability
Sample Space
The set of ALL possible outcomes for an event
Ways to display the sample space:List all possible outcomesTableTree diagram
You can also use multiplication to find the total number of possible outcomes.
EX: 2 types of bread x 3 sandwich fillings = 6 different sandwiches that can be made
Ex: List
On track and field day the students have a choice of either a tuna sandwich, turkey sandwich, or a peanut butter and jelly sandwich. They can have water or milk to drink. Create a list that shows all the possible combinations that the students can have for lunch.
