In one of Mendel's experiments with plants, 1064 offsprings consisted of 787 plants with long stems. According to Mendel's theory, 3/4 of the offspring plants should have long stems. Assuming that Mendel's proportion of 3/4 is correct, find the probability of getting 787 or fewer plants with long stems among 1064 offspring plants. compare answers with binomial and normal approximation.
