Understand the concept of probability: Probability measures how likely an event is to occur, and it ranges from 0 to 1, where 0 means the event cannot happen and 1 means the event is certain to happen.
Identify the event described: The problem asks for the probability of an event that is certain to occur, meaning it will happen every time without fail.
Recall the probability rule for a certain event: By definition, the probability of a certain event is always 1, because it is guaranteed to happen.
Express this mathematically: The probability of a certain event E is given by \(P(E) = 1\).
Conclude that no additional information is needed to determine this probability since certainty directly implies a probability of 1.
