5.82 Waste dump sites A federal agency is deciding which of two waste dump projects to investigate. A top administrator estimates that the probability of federal law violations is 0.30 at the first project and 0.25 at the second project. Also, he believes the occurrences of violations in these two projects are disjoint.

a. What is the probability of federal law violations in the first project or in the second project?

b. Given that there is not a federal law violation in the first project, find the probability that there is a federal law violation in the second project.

c. In reality, the administrator confused disjoint and independent, and the events are actually independent.

Answer parts a and b with this correct information.
