Show Hint
Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

- \( \frac{5}{7} \)
- \( \frac{4}{7} \)
- \( \frac{3}{7} \)
- \( \frac{1}{7} \)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The total number of balls is \( 3 + 4 + 7 = 14 \). The number of favorable outcomes (drawing either a red or a black ball) is \( 3 + 7 = 10 \). Thus, the probability is:
\[
\frac{10}{14} = \frac{5}{7}.
\]
