Final answer:
The choice that accurately completes the sentence is A. (.30)(.35). The probability of someone charging more than $2,000 per month is 30% and the probability of someone using a credit card that gives them a mile of air travel for every dollar they charge is 35%.
Step-by-step explanation:
The choice that accurately completes the sentence is A. (.30)(.35). This is because the question is asking for the probability of two independent events occurring, which can be calculated by multiplying the probabilities of each event. The probability of someone charging more than $2,000 per month is 30% and the probability of someone using a credit card that gives them a mile of air travel for every dollar they charge is 35%. So, the probability of both events happening is (.30)(.35) = 0.105 or 10.5%.
