Question

chapter 3: 3.1 probability terminology (concepts, simple, complements) homework
question 6
a group of people were asked if statistics teachers know the true meaning of life. 171 responded \yes\, and 347 responded
o\. find the probability that if a person is chosen at random, the person believes statistics teachers know the true meaning of life.
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 "no". So, $171 + 347=518$.

Step2: Calculate probability

The probability $P$ that a randomly - chosen person believes statistics teachers know the true meaning of life (i.e., those who responded "yes") is given by the formula $P=\frac{\text{Number of "yes" responses}}{\text{Total number of responses}}$. So, $P = \frac{171}{518}\approx0.3290$.

Answer:

$0.3290$
