16 Probability

So far, you have learnt to ask a RQ, identify different ways of obtaining data, design the study, collect the data describe the data, summarise data graphically and numerically, and understand the decision-making process.

In this chapter, you will learn about probability to describe the random nature of sample statistics. You will learn to:

explain probabilities.
apply the classical approach to probability in simple situations.
apply the relative frequency approach to probability in simple situations.
apply the subjective approach to probability in simple situations.
identify events that are independent.
