Brief Introduction about the chapter

We talk a lot about probability in our every day life, knowing or unknowingly. Each of us has some intuitive notion of this concept. For example, ponder over these statements:

“ There is a good chance that it will rain today ”

“ India is almost sure to win this T20 match against Pakistan ”

“ The stock market is likely to fall again soon ”

“ Issac Newton is probably the most influential human to have ever existed ”

We make innumerous statements of these sort everyday. There is an underlying “chance” element in each such statement. Have you ever paused and wondered why this chance element arises, and how our minds are able to quantify this chance element intuitively, without any mathematical knowledge whatsoever? If you haven’t, this chapter gives you a chance to do so!
