Question 1151221: Suppose a county’s recent health report gives a pet allergy prevalence of 0.13 for kids. There is a new at-home test kit for pet allergies on the market that provides families with a convenient way to test if children have a pet allergy. The probability that the test gives a positive result when a child really does not have a pet allergy is 0.06. The probability that the test gives a negative result when a child really does have a pet allergy is 0.12. The tree diagram shows the possible outcomes with the associated probabilities.
What is the probability of an incorrect test result? Give your answer as a decimal precise to two decimal places.

There is a 0.06+0.12=0.18 chance of an incorrect test result.
