Final answer:
Probability is a measure of the likelihood of an event occurring. For example, when tossing a fair coin, the probability of getting a head is 50 percent. It can also be used to predict the chance of genetic inheritance.
Step-by-step explanation:
Probability is a measure of the likelihood of an event occurring. It is used to study randomness and deals with the chance of an event occurring. For example, when tossing a fair coin, the probability of getting a head is 50 percent because there are only two possible outcomes - head or tail - and they are equally likely. Another example is the probability of alleles in genetic inheritance. Probability can be used to predict the chance of gametes and offspring having certain alleles based on the known probabilities of individual outcomes.
