Problem 5.125

When commercial aircraft are inspected, wing cracks are reported as nonexistent, detectable, or critical. The history of a particular fleet indicates that 70% of the planes inspected have no wing cracks, 25% have detectable wing cracks, and 5% have critical wing cracks. Five planes are randomly selected. Find the probability that a one has a critical crack, two have detectable cracks, and two have no cracks. b at least one plane has critical cracks.
