What is probability?
Probability is called the study of randomness, the probability that something may happen or chance that something may occur. It is sometimes expressed as a fraction between 0 and 1. It may also appear as a decimal or percent. Life is given in probabilities, the chance of rain or not, the side effects of a medication. Of course we look at dice, cards, and "wheel of fortune".
