According to Mendel’s theory, if tall and colorful plants are crossed with short and colorless plants, the corresponding probabilities are 9/16, 3/16, 3/16, and 1/16 for tall and colorful, tall and colorless, short and colorful, and short and colorless, respectively. If 8 plants are selected, find the probability that 1 will be tall and colorful, 3 will be tall and colorless, 3 will be short and colorful, and 1 will be short and colorless.(4 decimal digits)
