9. Objectives

10. At the end of the lesson, each learner should be able to:
Distinguish
experiment, outcome,
sample space and
event based on given
examples.
Illustrate an
experiment,
outcome, sample
space and event.
Appreciate the
basic concepts of
probability in real-
life situation.

11. Experiment
• is any planned process of data
collection.
Examples:
rolling a die
tossing a coin
drawing a marble out of jar

12. Outcome
• is the result of a single
trial of an experiment.

13. Sample
Space
• is the collection of all the
possible outcomes.
Examples:
In tossing a coin = {head, tail}
In rolling a die =

14. Events • is a subset of the sample space. It is
set of some of the possible outcomes
to which a probability is assigned.
Examples:
1. P(getting a 2 from rolling a die)
2. P(drawing a jack from deck of cards)
3. P(getting an odd number from rolling a die)
4. P(picking a black marble from a jar)

15. ACTIVITY

BOX WITH NUMBERS
DECK OF CARDS
BOX WITH LETTERS

16. • Name your experiment
• Do an experiment and give your first
5 outcomes
• Give the sample space
• Make at least 5 events

17. *Insert Perya pictures*

18. Evaluation
Ben is randomly picking numbers from a box with
numbers 1 to 20. On his first pick, he got number 17 and
on his second pick he got number 14. He also solved for
the probability of getting an even number and the
probability of getting a multiple of 5 from the box.
From this statement, give
• The name of the experiment
• Ben’s first and second outcome
• The sample space of his experiment
• The two events

19. Assignment
Give an example of experiment and give also its
outcomes, sample space and at least 5 examples of
its event.
