Question
![A group of students were asked if they carry a credit card. The responses are listed in the table.
| Class | Credit Card Carrier | Not a Credit Card Carrier | Total |
|-------------|---------------------|---------------------------|-------|
| Freshman | 13 | 47 | 60 |
| Sophomore | 14 | 26 | 40 |
| Total | 27 | 73 | 100 |
If a student is selected at random, find the probability that he or she is a sophomore and owns a credit card. Round your answers to three decimal places.
- A. 0.519
- B. 0.481
- C. 0.675
- D. 0.140
**Explanation:**
The table presents a breakdown of students by class (Freshman and Sophomore) and whether they carry a credit card. The total number of students surveyed is 100. Out of these, 14 sophomores carry a credit card. To find the probability that a randomly selected student is a sophomore with a credit card, use the formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{14}{100} = 0.140 \]
Therefore, the correct option is D. 0.140.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb8fa05ee-52b8-4b3d-a3d0-54c9685a9d54%2Fb87c2642-fe0a-4712-8f12-8faf6810c8aa%2Ffadlzps_processed.png&w=3840&q=75)
