WebThe probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A A is often written as P (A) P (A) . If P (A) > P (B) … Web14. Let A be an event, Pr be the probability measure. A has zero probability if Pr (A) = 0. A is impossible if A = ∅. Impossibility implies zero probability, but the reverse is false. Consider the real line R; if you randomly select a number x, the probability that x = 0 is 0, but this is not impossible.

WebTo summarise what we have learned till now, we know that If the probability of an event occurring is zero, it is called an impossible event. If the chance of an event occurring is 1, it is referred to as a certain event. The empty set ∅, on the other hand, is an impossible event, while the sample space S is a certain event.
