3) A candy company claims that 22% of the jelly beans in its spring mix are pink. Suppose that the candies are packaged at random in bags containing about 400 jelly beans. A class of students opens several bags, counts the various colors of jelly beans, and calculates the proportion that are pink. In one bag, the students found 19% of the jelly beans were pink. a) What is the probability that a bag will contain fewer than 19% pink...
