When mendel conducted his famous hybridization experiments, he used peas with green pods and yellow pods. one experiment involved crossing peas in such a way that 25% (or 145) of the 580 offspring peas were expected to have yellow pods. instead of getting 145 peas with yellow pods, as expected, he got 152. assuming that mendel’s 25% rate is correct, estimate the probability of getting at least 152 yellow pea pods among the 580 offspring peas using the normal distribution approximation. then calculate the exact probability using the binomial distribution. compare the two probabilities.
