Due to the fact that the events cannot occur concurrently, their joint probcapability is constantly zero.

2. Rule of Addition

The preeminence of addition enables determining the probability that at leastern one of the occasions occurs (it is known as the union of the events). For mutually exclusive occasions, the ascendancy of addition defines the following:


The union probcapacity of the events is uncovered by summing just the individual probabilities of each event because tbelow is a zero probcapability that both events deserve to take place at the same time.
