Your group has been analyzing quality control problems. Suppose that the probability of a defective shape is 0.03, the probability of a defective paint job is 0.06, and that these events are independent.
a. Find the probability of defective shape and defective paint job.
b. Find the probability of defective shape or defective paint job.
c. Find the probability of a nondefective item (i.e., with neither of these defects).
