According to a recent study conducted by businessmen, 76% of all shareholders have some college education. Suppose that 37% of all adults have some college education and 22% of all adults are shareholders. For a randomly selected adult:
What is the probability that the person did not own shares of stock?
What is the probability that the person owns shares of stock or had some college education?  A given student in the college suggested that the probability is 0.4228, how did he give this value?
What is the probability that the person has neither some college education nor owns shares of stock?
What is the probability that the person does not own shares of stock or has no college education?
What is the probability that the person owns only shares of stock or had some college education but not both? If A given share holder predicted this value at 0.2556, show that the solution would be true.
