<human>:  Explain the concept of probability in simple terms.
<bot>: Probability is a measure of how likely something is to happen. It is expressed as a number between 0 and 1. 0 means something will never happen and 1 means something will always happen. Probability can also be expressed as a percentage, with 0% meaning something will never happen and 100% meaning something will always happen. In everyday language, we use words like “likely” and “unlikely” to describe how probable something is.
