Assume 42​% of us have Group O blood. A hospital is conducting a blood drive because its supply of Group O blood is​ low, and it needs at least 128 donors of Group O blood. If 260 volunteers donate​ blood, estimate the probability that the number with Group O blood is at least 128. Is the pool of 260 volunteers likely to be​ sufficient?
