If P(E) = 0.05, what is the probability of ‘not E’?
Question
If P(E) = 0.05, what is the probability of ‘not E’?
Solution
The probability of an event not happening, often denoted as 'not E' or 'E complement', is calculated by subtracting the probability of the event from 1.
So, if P(E) = 0.05, then the probability of 'not E' is calculated as follows:
P(not E) = 1 - P(E)
Substituting the given value:
P(not E) = 1 - 0.05
So, P(not E) = 0.95
Therefore, the probability of 'not E' is 0.95.
