The probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license is 0.27.
How to find the probability
To find the probability that the fisher chosen from Clearwater Park did not have a license and the fisher chosen from Mountain View Park had a license, consider the number of favorable outcomes and the total number of possible outcomes.
From the given information:
Clearwater Park: 21 had a license, and 9 did not (total of 30 fishers).
Mountain View Park: 18 had a license, and 2 did not (total of 20 fishers).
To calculate the probability, multiply the probability of choosing a fisher without a license from Clearwater Park (9/30) by the probability of choosing a fisher with a license from Mountain View Park (18/20):
P = (9/30) * (18/20)
Simplifying the expression:
P = 3/10 * 9/10
P = 27/100
P = 0.27
Therefore, the probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license is 0.27.
Of the people who fished at Clearwater Park today, 21 had a fishing license, and 9 did not. Of the people who fished at Mountain View Park today, 18 had a license, and 2 did not. (No one fished at both parks.)Suppose that one fisher from each park is chosen at random. What is the probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license?
