Final answer:
The exact maximum credit card refund amount is not provided, but the usage of a credit card giving air miles for every dollar spent and the event of charging more than $2,000 per month appear to be related, based on the given information.
Step-by-step explanation:
The question regarding the maximum credit card amount that can be refunded does not provide enough context or specific details to determine an exact answer. However, based on the given information, we can discuss the probability and independent events in relation to credit card usage. According to the provided statistics, 35 percent of respondents use a credit card that offers an air mile for every dollar spent, and 30 percent charge more than $2,000 per month. Among those who charge more than $2,000, 80 percent use a card that gives air miles. If we want to find out whether using a credit card that gives air miles and charging more than $2,000 per month are independent events, we would need to look at the probability of both events occurring together and separately.
To characterize two events as independent, the probability of both events occurring together should be equal to the product of their individual probabilities. This can be represented as P(A and B) = P(A) × P(B), where P(A and B) is the probability of both events happening simultaneously, P(A) is the probability of event A occurring, and P(B) is the probability of event B occurring.
It is important to check with the ticketing location or review the terms and conditions of your credit card to determine any limitations on refund amounts.
