ALEKS Probability Answers: Two Independent Fisher Selections

The two selections are independent: 48/80 of Clearwater fishers have licenses and 45/90 of Mountain View fishers do not, giving an exact probability of 3/10.

Question

Of the people who fished at Clearwater Park today, 48 had a fishing license, and 32 did not. Of the people who fished at Mountain View Park today, 45 had a license, and 45 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 had a license and the fisher chosen from Mountain View did not have a license?Do not round your answer. (If necessary, consult a list of formulas.)

Evidence boundary

This calculation uses only the 48, 32, 45, and 45 counts in the locked question version and assumes an equally likely random selection from each park's listed population. It does not use values from other algorithmically generated ALEKS variants.
