Final answer:
The shoppers in the large shopping mall can be categorized in 8 different ways based on gender, age, and payment method.
Step-by-step explanation:
The shoppers in the large shopping mall can be categorized as male or female, over 30 or 30 and under, and cash or credit card shoppers. To calculate the total number of ways the shoppers can be categorized, we multiply the number of options for each category. In this case, we have 2 options for gender (male or female), 2 options for age (over 30 or 30 and under), and 2 options for payment method (cash or credit card).
Therefore, the total number of ways the shoppers can be categorized is 2 * 2 * 2 = 8.
So, the shoppers can be categorized in 8 different ways based on these criteria.
