Probabilities closer to 0 indicate that an event is less likely to occur. Probabilities closer to 1 indicate that the event is more likely to occur. occurrence in a sample of n observations.

Detailed explanation-2: -In epidemiology, probability theory is used to understand the relationship between exposures and the risk of health effects.

The insurance industry and markets use actuarial science to determine pricing and make trading decisions. Governments apply probabilistic methods in environmental regulation, entitlement analysis, and financial regulation.
