Question

a group of people were asked if some psychics can help solve murder cases. 163 responded \yes\, and 387 responded
o\. find the probability that if a person is chosen at random, the person believes some psychics can help solve murder cases. probability = (round to 4 decimal places)

Explanation:

Step1: Calculate total number of people

The total number of people is the sum of those who responded "Yes" and those who responded "No". So, $163 + 387=550$.

Step2: Calculate the probability

The probability $P$ that a randomly - chosen person believes some psychics can help solve murder cases is the number of people who responded "Yes" divided by the total number of people. So, $P=\frac{163}{550}$.

Answer:

$0.2964$
