- A researcher believes that about 74% of the seeds planted with the aid of a new chemical fertilizer, will germinate. He chooses a random sample of 90 seeds and plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that Atmos 66 of the 90 seeds will germinate.
