In studies for a​ medication, 12 percent of patients gained weight as a side effect. Suppose 740 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that ​(a) exactly patients will gain weight as a side effect.
​(b) no more than patients will gain weight as a side effect.
​(c) at least patients will gain weight as a side effect. What does this result​ suggest?
