Probability is a branch of mathematics that deals with calculating the likelihood of a given event’s occurrence, which is expressed as a number between 1 and 0. An event with a probability of 1 can be considered as a certainty.

In this chapter, you will learn about events and probability. An event for an experiment is the collection of some outcomes of the experiment. In this chapter, you will get various scenarios where you will have to calculate the probability of the occurrence. Many interesting activities are given in this chapter to make the process of learning more exciting.

These activities can be performed with the help of coins. You will also learn how and when to use the empirical formula.  This chapter is very important as it will help you in your studies.
