What is Probability?

• The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
• An event’s probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event’s impossibility and 1 denotes certainty.
• The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, “heads” and “tails,” are equally likely to occur. As a result, the probability of either occurrence is half.
