Question

The probability of an event ________ occurring is the complement. The probability of the event and its complement have a sum of___.

Answer 1

Answer:

Not, 1

Step-by-step explanation:

The complement of an event denoted as A', can be interpreted as not A. This means that elements not belonging to a A. In probabilistic term, if we have an event A, the complement is f A is the probability that event A does not occur.

The sum of an event A and its corresponding complement must equal to 1.

This is given by the complement rule ;

P(A) + P(A') = 1

Hence, P(A') = 1 - P(A)
