What is union of events?
Union of events: The event that at least one of two or more given events occurs, written A or B. It contains every outcome that lies in any of the events. Its probability is found with the addition rule.
Union of events: an example
With a die, the union of 'even' {2,4,6} and 'greater than 4' {5,6} is {2,4,5,6}.
