Question

a group of people were asked if marilyn monroe had an affair with jfk. 254 responded \yes\, and 418 responded
o\. find the probability that if a person is chosen at random, he does not believe marilyn monroe had an affair with jfk. enter as a fraction.

Explanation:

Step1: Calculate total number of people

The total number of people is the sum of those who responded "yes" and "no". So, $254 + 418=672$.

Step2: Determine number of people who don't believe

The number of people who don't believe (responded "no") is 418.

Step3: Calculate the probability

The probability $P$ that a randomly - chosen person doesn't believe is the number of people who don't believe divided by the total number of people. So, $P=\frac{418}{672}=\frac{209}{336}$.

Answer:

$\frac{209}{336}$
