Sample Space and Outcomes
Vocabulary
• Experiment - Activity in which results are observed
Each observation
Each result
The set of all possible outcomes of an experiment
• Sample space -
• Outcome -
• Trial -
Impossible Certain
0 1
Even chance
12
Unlikely Likely
Probabilities never have values less than 0 or more than 1 (remember 100 % is the same as 1 whole).

Experiment Sample Space
For the experiment to be fair or equally likely, the outcome has to be the same size
flipping a coin heads, tails
rolling a number cube 1, 2, 3, 4, 5, 6
whole numbersguessing the number of marbles in a jar
Outcome is the predicted result of an event
Outcomes – ( Red, Orange , purple, yellow, green)
2. Spin this spinner
1. Roll a die – outcomes (1,2,3,4,5,6)
3. Toss a coin – outcomes (heads, tails)
Sample space is the ordered listing of all possible outcomes.
3. List the possible outcomes if you toss a penny twice.
