The results of the study indicated that the probability that a consumer is 18 to 24 years old and uses a Visa Card when making a purchase is 0.0703 and the probability that a consumer is older than 24 and uses a Visa card when making a purchase is 0.2997. Also, the probability that a consumer is 18 to 24 years old is 0.14. (Assume that Visa customers are either 18-24 years old or older than 24).1.
