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.
• The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is .
