When we perform an experiment, the sample space refers to all the possible outcomes.

Let’s consider tossing a coin and rolling a dice and draw a table to show all the possible outcomes that can occur. As each of these outcomes are mutually exclusive, each outcome has an equal probability of occurring. So what is the probability of getting a Head and a 6? What is the probability of getting a tail and an even number?
