Final answer:
The intuitive definition of probability is the likelihood or chance that an event will occur. In mathematics, probability is used to study randomness and calculate the chance of an event occurring.
Step-by-step explanation:
The intuitive definition of the probability of an event is the likelihood or chance that the event will occur. It is a measure of how likely an event is to happen. In mathematics, probability is used to study randomness and calculate the chance of an event occurring.
To calculate the probability of an event A when all outcomes in the sample space are equally likely, count the number of outcomes for event A and divide by the total number of outcomes in the sample space. This is known as the theoretical probability of A.
For example, if you toss a coin, the chance of a head turning up is 50 percent. This is because a coin has only two sides, so there is an equal chance of a head or tail turning up on any given toss.
