When commercial aircrafts are inspected, wing cracks are reported as non-existent, detectable, or eritical. The history of a particular fleet indicates that 60% of the planes inspected have no wing cracks, 30% have detectable wing cracks, and 10% have critical wing cracks. Three planes are randomly selected. Find the probability that one has a critical crack, one have detectable cracks, and one have no cracks.
