A researcher believes that about 72% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 125 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that at least 89 of the 125 seeds will germinate. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.
