Answer: Mutually exclusive
Step-by-step explanation:
In probability theory and logic, two propositions or events are disjoint or mutually exclusive if both events cannot occur at the same time. An example is the outcomes derived from the single toss of a coin which either be head or tail
In the project example given, the theory used is called mutually exclusive since both projects can not be chosen at the same time and it is only one project at w time. Mutually exclusive events are also called independent events since they have no effect on the viability of the other options.
