A scientist conducted a hybridization experiment using peas with green pods and yellow pods. He crossed peas in such a way that 25% (or 149) of the 596 offspring peas were expected to have yellow pods. Instead of getting 149 peas with yellow pods, he obtained 151. Assume that the rate of 25% is correct.
Find the probability that among the 596 offspring peas, exactly 151 have yellow pods.
Find the probability that among the 596 offspring peas, at least 151 have yellow pods.
