Final answer:
The law of large numbers is the mathematical concept that states that the more times an event is repeated, the more predictable the outcome becomes.
Step-by-step explanation:
The mathematical concept that the more times an event is repeated, the more predictable the outcome is known as the law of large numbers. This law states that as the number of trials in a probability experiment increases, the difference between the theoretical probability of an event and the relative frequency probability approaches zero. In other words, the more times the experiment is repeated, the closer the observed relative frequency will be to the expected theoretical probability.
