"Two events A and B are said to be mutually exclusive if AB is a null event" Null event is the event which does not have any elements in it. Rolling an ordinary six-sided die is a familiar example of a random experiment, an action for which all possible outcomes can be listed, but for which the actual outcome on any given trial of the experiment cannot be predicted with certainty.In such a situation we wish to assign to each outcome, such as rolling a two, a number, called the probability of the outcome . . We want to find the probability of rolling a 1 on the die and flipping heads on the coin. The use of this rule is to . For example, "Find the probability that a student is taking a mathematics class or a science class." That is expressing the union of the two sets in words.

Intersection Definition & Meaning - Merriam-Webster You can do that with the terms div but first let's go over a simple example first to demonstrate how that works. When events are independent, we can use the multiplication rule, which states that the two events A and B are independent if the occurrence of one event does not change the probability of the other event. The solutions using scroll events always have issues similar to using scroll events for other purposes. Event E: the outcome being an even number.
