CHAPTER 7 : PROBABILITIES
7.1 Introduction
The theory of probability was
developed towards the end of the 18th century and its history suggests
that it developed with the study of games and chance, such as rolling
a dice, drawing a card, flipping a coin etc. Apart from these, uncertainty
prevailed in every sphere of life. For instance, one often predicts:
"It will probably rain tonight." "It is quite likely
that there will be a good yield of cereals this year" and so
on. This indicates that, in layman’s terminology the word ‘probability’
thus connotes that there is an uncertainty about the happening of
events. To put ‘probability’ on a better footing we define it. But
before doing so, we have to explain a few terms."
