What does probability remind you of? Coin **tosses** and coloured **balls**? Your Maths teacher must have done a fine job!

Sometimes you say something like, "Having known Vinay for 3 years, I am 70% sure that he is not ripping me off on this deal". The 70% here is a probability too. But, it is being used in a very **different sense** than coin tosses and balls.

How do we **reconcile** these two concepts of probability? We will learn about it in this module.

You may also learn about how you can be more successful on your **second date**. Mathematically speaking, of course!
