Here we introduce the concepts of probability. 2 Definitions of probability There are several approaches to defining a probability: • We can take the subjective or personal view of probability, which is to regard it as a measure of the strength of belief an individual has that a particular event will occur. For example, ‘That cow has a 60% chance of calving tonight’. 4) when it represents the extent to which it is supported by the available evidence.

Gauss, an 18th century German math- 35 ematician, is the most important of the continuous distributions because of its role in sampling theory, which we consider in Chapter 4. The term ‘Normal’ is not meant to imply that the probability distribution of the random variable is typical, even though it is a good approximation to the distribution of many naturally occurring variables, or that it represents a ‘non-diseased’ group of individuals. To distinguish the Normal distribution from any other interpretation of normal, we use an upper case N in the former instance throughout this book.
