![You've Got Cooties! A certain medical test has the following reliability: if a person
has cooties the test will show positive with probability 0.95. If a person does not
have cooties, the test will show negative with probability 0.6. Overall, 10% of the
population has cooties. Give your answers as percentages with two decimal digits,
e.g. 93.42%.
Hint: Fill in this tree diagram. C = person has cooties. F = person is cooties "free". P =
test is positive for the disease. N = test is negative for the disease.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F72d566d7-2c34-4198-bd06-55915f8333dd%2F5902ed71-e6a7-4c80-9b85-f33d005c3838%2Fagtx94_processed.jpeg&w=3840&q=75)
