the new lesson Greetings
Checking of attendance
(Teacher will set the classroom to a conducive learning
atmosphere, safe and secure learning environment through
checking of attendance and setting of guidelines.)
(Teacher will have a friendly implementation of policies,
guidelines and procedures for the entire class.)
Setting of class rules/guidelines
(Everyone in the classroom is encouraged to remember the
rules.)
1. Respect to one another
2. Listen attentively
3. Do not talk while the teacher are discussing in front
unless your name is called.
4. Raise your right hand if you want to answer.
5. Observe classroom cleanliness
Ask students about their understanding of the previous
lesson to know whether they still remember it.
B. Establishing a
purpose for the MOTIVATION
lesson
Directions: Read the situation carefully and answer the
given questions below.
Every morning around 9:00 – 10:00 AM, Mrs. Reyes sells
affordable homemade snacks. Each serving contains
food and drink. Foods consist of banana cake (B) and
pancake (P) while drinks consist of juice (J), hot
chocolate (H), and fresh milk (M).
Questions:
1. How many choices of foods are there?
2. How many choices of drinks are there?
3. What are the different possible servings Mrs. Reyes
can offer to her customers?
4. How many different possible servings are there in all?
C. Presenting
examples/instances Objectives:
of the new lesson
At the end of the lesson, the learners are expected to;
Determine the probability of simple events.
Identify the probability of simple events through a given
sample events.
Solve real-life problems using the principles of counting
techniques and probability.
(Teacher ask some question.)
Have you at a certain time asked yourself the following
questions?
What are my chances of getting the correct answer in a
True/False-type question? Multiple choice-type question?
Should I bring my umbrella tomorrow?
Have
you at a certain
time asked
yourself the
following
questions?”
“What are my
chances of getting
the
correct answer in
a True/False-type
question? Multiple
choice-type
question?
or should I bring
my umbrella
tomorrow?”
These questions will be answer by your own as we go through
with our lessons.
Probability is the measure of likelihood or chance that an event
will happen or occur. For experiments where each outcome is
equally likely to occur, it is the ratio of the number of ways an
event can occur to the number of all possible outcomes
Probabilities are written as fractions or decimals from 0 to 1 or
as percent from 0% to 100%. The higher an event‘s probability,
the more likely that the event is to happen.
Presented below is the probability line showing the probability of
an event followed by the probability rules.
Probability Rules
1. If an event has a probability of 0, or 0%, then it will never
happen or it is impossible to happen.
2. If an event has a probability of 0.5 or 50%, then the event has
the same chance or even chance to happen or not to happen.
3. If an event has a probability of 1, or 100%, then the event is
certain to happen.
4. The sum of the probabilities of all the outcomes of an
experiment is 1.
Probability of simple event can be calculated using the formula.
D. Discussing new
concepts and Example 1 - Probability in Experiment Involving Coin
practicing new skills If you flip a coin once, what is the probability of getting a
#1 head?
n(E)
P ( E )=
n(S)
Where: P(E) is the probability of the event (Head).
n(E) is the number of getting a head.
n(S) is the total number of possible outcomes.
1
P ( H )=
2
So, the probability of getting a head in flipping a coin
1
once is .

E. Discussing new
concepts and Example 2 - Probability in Experiment Involving Die
practicing new skills Given a standard die, find the probability of the following
#2 events when rolling a die once:
a) getting a 4
b) getting an odd number
c) getting a 7
F. Developing mastery

remediation
