3. Objectives:
Counts the number of occurrences
of an outcome in an experiment: (a)
table; (b) tree diagram; (c) systematic
listing; and (d) fundamental counting
principle.
4. Activity1
Directions: Read each statement or
questions below carefully and choose the
correct answer provided inside the box.
Write your answer on a separate sheet.

Statistics
1. It is an activity or process with an
observable result.
2. It is the observable result in your
experiment.
3. It is the set of all results of an experiment
or the set of all outcomes.
6. 4. It is a subset (a part) of your sample
space.
5. It is a specific outcome, just one of the
possible outcomes of the experiment.
6. It is the measure of the likelihood that an
event will occur.
9. Counting Techniques
Grid Table- gives us excellent visual displays of sample spaces. It consists
of columns and rows that represent separate types of events. Grid table is
helpful when the experiment is a two-part task.
Tree diagram- is a graphic organizer used to list all possibilities of a sequence of events in
a systematic way.
The fundamental principle of counting-of one thing can occur in m ways
and a second thing can occur in n ways, and a third thing can occur in p
ways, and so on, then the sequence of things can occur in m x n x p x …
ways
Systematic Listing- is the process of getting the sample space of an
experiment where the outcome of an event is listed systematically or in an
organized manner.
