Numerical way of describing the likelihood/possibilities of a certain event from happenening.
Probability
A chart that organizes information in rows and columns.
Table
P(2 HEADS) = 2/3
If you roll 3 fair dice, what is the probability that the sum of the numbers on the dice is greater than 10?
37/72
If Toph had to pick between his two crushes: Claire and Lhean, what is the probability that it will be Lhean?
1/2
The "ACTION" or "PROCESS"
Experiment
A simple way of representing a sequence of events.
Tree Diagram

4/5
If you roll two fair dice, what is the probability that the sum of the numbers on the two dice equals 7?
1/6
If Clint had 4 bottles milk, 5 bottles of water, and 3 cans of soda, what is the probability that he will open a bottle of orange juice?
0/12
Any possible result of the experiment.
Outcome
Outcomes that can be listed in an organized or SYSTEMATIC way.
Systematic Lining

5/16
If Luke had to choose a favourite character from AMNSE, what is the probability that it will be Andrada, out of all the 17 characters?
1/17
The SET of all possible outcomes.
Sample Space
Used to count the total number of possible outcomes in a situation.
Fundamental Counting Principle
Marco has 2 pieces of chocolate, 3 pieces of candy, and 5 pieces of biscuit. What is the probability that he will pick a piece of candy if he chooses one piece from all his snacks?
P(PIECE OF CANDY) = 1/10
If you draw one card from a standard deck of 52 playing cards, what is the probability that the card is not a queen?
12/13

0/10
Is A subject or THE subject of the sample space.
Event
These 4 are used to count the number of occurences of an outcome in an experiment. List them.
