Question

a group of people were asked if marilyn monroe had an affair with jfk. 152 responded \yes\, and 168 responded
o\. find the probability that if a person is chosen at random, the person believes marilyn monroe had an affair with jfk. probability = (round to 4 decimal places)

Explanation:

Step1: Calculate total number of people

$152 + 168=320$

Step2: Calculate the probability

The probability $P$ that a person believes Marilyn Monroe had an affair with JFK is the number of people who responded "Yes" divided by the total number of people. So $P=\frac{152}{320}$
$P = 0.4750$

Answer:

$0.4750$
