ANALYSIS

7

1. How can we identify whether an event is
impossible or possible to happen?
2. Are there any words we can use as hint to
state the likelihood of an event?
3. Can we use it concept to predict or have
assumption?
4. Is it possible for us to measure the
likelihood using mathematics?
5. How can we use this concept in other
subject areas such as in English, Science?

OBJECTIVES

8

At the end of the period, you must be
able to…
1. illustrate probability of simple
events.
2. finds probability of simple events.
3. solve problems involving simple
events probability.
4. recognize the importance of
probability in three Major Subjects.

PROBABILITY OF

SIMPLE EVENT

PROBABILITY?

WHAT IS

PROBABILITY?

- Probability is the
chance that some event
will happen.

- It is the ratio of the
number of ways a
certain event can occur
to the number of
possible outcomes

WHAT IS

VOCABULARY

7

§Outcome – one possible result of a probability.

§Sample Space – the list of possible outcomes for a probability event.

§Random – outcomes that occur at random if each outcome is equally likely to occur.

VOCABULARY

7

§Simple Event – a specific outcome or type of outcome.

REMEMBER : The sum of the probabilities of Simple events is 1.
