## Content

### ACTIVITY: To predict the likelihood of events in everyday life [LO 5.8]

1. Work with a friend. Decide whether the following is certain, possible or impossible. Put a tick in the appropriate column:

 Certain Possible Impossible 1.1 It will rain on Wednesday. 1.2 If you throw a die, it will land on 3. 1.3 Sunday comes before Monday. 1.4 The netball team will win their game. 1.5 You can fly from Durban to Cape Town in 15 minutes. 1.6 I will get full marks for my next test. 1.7 There will be no school holidays next year. 1.8 I will turn 10 on my next birthday. 1.9 Thursday comes before Wednesday. 1.10 I am going to win R1 000.00.

DID YOU KNOW?

4 You were actually estimating the probability of things happening or not. We can link numbers to the estimations.

A probability of one means that the event will definitely take place.

A probability of nought means that the event will definitely not take place.

We can determine the probability of something taking place as follows:

The number of times that the event can take place

Total number of possibilities

The probability of taking a red ball out of a container holding 2 red and 3 blue balls

therefore is:

(there are 2 red balls)

(there are 5 balls altogether)

## Assessment

Learning Outcome 5:The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.

Assessment Standard 5.8: We know this when the learner predicts the likelihood of events in daily life based on observation, and places them on a scale from 'impossible' to 'certain'.
