Lessons On Probability

What Is Probability?

Probability is the study of chance or the likelihood of an event happening. Directly or indirectly, probability plays a role in all activities.

For example, we may say that it will probably rain today because most of the days we have observed were rainy days. However, in mathematics, we would require a more accurate way of measuring probability.

Probability in math is a measure of the likelihood that an event will occur. It is quantified as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. The higher the probability of an event, the more likely it is that the event will happen.
