Definition of Probability
A probability tells you the chance that something will happen. In other words, it tells you how likely it is for a given event to happen.
Sometimes, probabilities are measured using percentages or fractions. For example, an event might be given a \(25\%\) chance or a \(\dfrac{1}{4}\) chance.
On other occasions, probabilities might be described in words like "unlikely", "possible", "50-50 chance", "likely" and "certain".
For example, the weather forecast might state that there's a \(90\%\) chance of rain tomorrow. Then, it is likely to rain tomorrow.
If the weather forecast says there's a \(100\%\) chance of rain tomorrow, it is certain that it will rain tomorrow.
