Let the three mutually independent events $C_{1}, C_{2}$, and $C_{3}$ be such that $P\left(C_{1}\right)=P\left(C_{2}\right)=P\left(C_{3}\right)=\frac{1}{4} .$ Find $P\left[\left(C_{1}^{c} \cap C_{2}^{c}\right) \cup C_{3}\right]$

Key Concepts

Intersection and Union of Events

Calculating the probability of intersections (simultaneous occurrences) of events and unions (at least one occurring) requires understanding how events combine. For independent events, the intersection probability is the product of their individual probabilities, and for unions, the inclusion?exclusion formula ensures that overlapping probabilities are properly accounted for.

Inclusion?Exclusion Principle

The inclusion?exclusion principle is used to calculate the probability of the union of two or more events. It involves adding the probabilities of the individual events and then subtracting the probability of their intersection, thereby correcting for the overcounting that occurs when events overlap.

Independent Events

This concept refers to events whose outcomes do not affect one another. When events are independent, the probability of the intersection of any subset of them is equal to the product of their individual probabilities. This principle is crucial when calculating the probability of combined events when their outcomes are unrelated.

Complement Rule

The complement rule is a fundamental idea in probability stating that the probability of an event not occurring is 1 minus the probability of the event occurring. It is particularly useful when it is easier to compute the probability of the complement of an event rather than the event itself.
