Question

The probability that Patricia will win the election is 9/14

. What is the probability that she will not win the election?

Answer 1

If A is an event then P(A) + P(A") = 1 (probability A occurring + probability A not occurring = 1)

Here event A is Patricia will win the election and P(A) is equal to 9/14 so:

P(A) = 9/14 and we need to find P(A') which is probability Patricia will not win the election.

Using the equation at the top:

9/14 + P(A') = 1

and P(A') = 5/14
