Webb20 feb. 2024 · The task here is to prove that the probability of A will always lie between 0 and 1 i.e. 0 <= P (A) <= 1. Solution: Consider event A. Below are the steps for the proof of the above problem statement-. According to axiom 1, the probability of an event will always be greater than or equal to 0. WebbThe probability of an event A is calculated by the following formula: If there is no ambiguity in the occurrence of an event, then the probability of such an event is equal to 1. In other words, the probability of a certain event is 1. If an event has no chances of occurring, then its probability is 0.
