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.

10. Activity 3
Directions: For 10 minutes analyze
and complete the table following the
given example below. Copy and
answer in a ½ sheet of paper.

Pants B, Shirt 1
Total number of possible outcomes: 10

13. C.Using systematic listing
S = {Pants A, Pants B, _____, _____,
______, _____, _____ }

14. Activity 4
1. How did you complete the table and tree diagram depicting
the effects of a combination of pants and shirts based on the
exercise you did earlier?
2.After completing the table, how did you determine the
number of occurrences of an outcome in a combination using a
table and a tree diagram?
3.What did you do to arrive on your answer in systematic
listing?
4. Why did you come up with the number filled in the blank?
5.In your own opinion, what is the importance of knowing the

15. Counting Techniques-Systematic Listing
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.
Example 1: Consider a Club N with five members:
N= [ Andy, Bill, Cathy, David, Evelyn] or as a shortcut,
N= [ A, B,C,D,E]
In how many ways can this group select a president (assuming all members are
eligible)?
The task in this case is to select one of the five members as president. It is a One-part
task.

16. Example 2:
For tossing a single six-sided die, the typical
sample space is {1,2,3,4,5, and 6} (in which the result
of interest is the number of pips facing up). This
method is one-part tasks; the results for simple tasks
consisting of one part can often be listed easily.

17. Counting Techniques-Grid Table
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.

18. Example 1: Determine the number of two-digit
numbers that can be written using digits from the set
(1,2, and 3). This task consists of two parts: choose a
first digit and choose a second digit. The results for a
two-part task can be pictures in a product table such as
Table 1. From the table we obtain our list of possible
results: 11, 12, 13, 21, 22, 23, 31, 32, and 33. There are
nine possibilities.

19. Table 1
Second
digit
1 2 3
First
digit
1 11 12 13
2 21 22 23
3 31 32 33

20. Counting Techniques-Tree Diagram
Tree diagram- is a graphic organizer used to list all
possibilities of a sequence of events in a systematic way.
Example: The number of three-digit numbers that
can be written using digits from the set {1, 2, 3},
assuming that repeated digits are allowed. The task of
constructing such a number has three parts: select the
first digit, select the second digit, and select the third
digit.

21. As we move from
left to right through
the tree diagram in
Figure 1, the tree
branches at the first
stage to all
possibilities for the
first digit.
Then each first-
stage branch
again branches, or
splits, at the
second stage, to
all possibilities
for the second
digit.
Finally, the
third-stage
branching
shows the
third-digit
possibilities.
The list of possible results (27 of them) is shown in Figure 1.

22. The Fundamental Counting
The Fundamental Principle of Counting
If 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
Example 1: In how many ways can a boy and a girl be
selected from a group of 5 boys and 4 girls?

23. Solution: The boys can be selected in 5 ways while the girls can be selected in 4
ways. Hence: 5 times 4 = 20 ways
Example 2: A and E Bakery serves two desserts; a cake and a pie. They also serve
three beverages: coffee, tea, and juice. Suppose you choose one dessert and one
beverage. How many possible outcomes are there?
Solution:
There are six possible outcomes.
Using the Fundamental Principle of Counting, we have:
{No. of Desserts} x {No. of Beverages} = {No. of Possible Outcomes}
2 x 3 = 6

listing, Grid Table, Tree diagram, and counting
