Answer :
Final answer:
The probability that a randomly selected person from the survey has encountered fraudulent charges on their credit card is 0.69 (69 people out of 100). Hence, the correct answer is a) 0.69.
Explanation:
The question relates to the concept of probability in mathematics. When a survey states that 69 percent have encountered fraudulent charges on their credit card, it is saying that out of every 100 people surveyed, 69 have encountered such charges.
Probability is typically expressed as a decimal or fraction between 0 and 1, where 0 means the event does not happen and 1 means that it happens every time. In this case, the probability that a randomly selected person from this survey has encountered fraudulent charges is indeed 0.69 or 69/100. So, the answer would be a) 0.69.
