Question

What is probability of an event occurring to the probability that it will not occur?

Answer 1

If you know the probability of an event occurring, it is easy to compute the probability that the event does not occur. If P(A) is the probability of Event A, then 1 - P(A) is the probability that the event does not occur. For the last example, the probability that the total is 6 is 5/36.

$\LARGE\sf\red{Impossible\:Event}$

Impossible Event:- An impossible event is an event that cannot happen. E is an impossible event if and only if P(E) = 0. In flipping a coin once, an impossible event would be getting BOTH a head AND a tail.
