Question

Define the union of two events. Choose the correct answer below. A. The union of two events A and B is the event that occurs if both A and B occur on a single performance of an experiment. B. The union of two events A and B is the event that occurs if either A or B​ (or both) occurs on a single performance of an experiment. C. The union of two events A and B is the event that occurs if only one of A or B occurs on a single performance of an experiment. D. The union of two events A and B is the event that occurs if neither A nor B occurs on a single performance of an experiment.

Answer 1

Explanation:

Given the elements in even A and event B, the union of the two events is a combination of the elements in event A and event B. The union of events follow the addition rule of probability. This means that it contains all elements in event A or event B or both

The correct option is

The union of two events A and B is the event that occurs if either A or B​ (or both) occurs on a single performance of an experiment.
