Assume that 40 percent are of type A, 30 percent of type B, and 30 percent of type C. It is known that 40 percent of seeds of type A, 45 percent of type B, and 75 percent of type C have germinated. A seed is selected at random. If the seed has germinated, what is the probability that it is of type A?
