Wilpen Company a price setting firm produces nearly 80 percent of all tennis balls purchased in the United States. Wilpen estimates the U.S demand for its tennis balls by using the following linear specification:
To find the probability of picking a college junior who prefers cheese, you need to divide the number of college juniors who prefer cheese (5) by the total number of college juniors (29).
So the probability of picking a college junior who prefers cheese is:
Probability = Number of college juniors who prefer cheese / Total number of college juniors
Probability = 5 / 29
Now you can calculate the probability:
Probability ≈ 0.1724 or 17.24%
Therefore, the probability that a randomly picked college junior at State University prefers cheese is approximately 0.1724 or 17.24%.
