The probability that an event will not happen is P(E^ prime )=0.56 . Find the probability that the event will happen.

Answer 1

The probability that an event does not occur is always equal to 1 minus the probability that the event occurs, because the probability of an event combined with the probability of the event not occurring is equal to all possible outcomes, which has a probability of 1.

This means that:

P(E) = 1 - P(E prime)

And if P(E prime) = .56, we can substitute this value into the equation to get:

P(E) = 1 - .56 = .44

So we can figure out that P(E) = .44
