Explanation:
A probability function, also called a probability distribution, is a mathematical function that describes the probabilities of different outcomes for a given random variable. It tells us how likely it is for a certain event to occur, given all the possible outcomes. For example, a probability function could describe the likelihood of getting a certain number when rolling a die. In this case, the possible outcomes are 1, 2, 3, 4, 5, and 6, and the probability of each outcome is 1/6. So, the probability function for rolling a die would be a series of values that each represent the probability of a certain outcome.
