One residence is randomly selected. Determine each of the following. Hat is the probability that the randomly selected residence has neither detectable levels of lead nor detectable levels of radon. a. b. C. What is the probability that the randomly selected residence has either detectable levels of lead or detectable levels of radon (or has detectible levels of both). What is the probability that the randomly selected residence has exactly one of these concerns (either detectable levels of lead or detectable levels of radon but not both).
