A pond contains 200 fishes of which 40 are marked. A second pond contains 300 fishes of which 50 are marked. One fish is drawn from each of the ponds. What is the probability that the fishes drawn are both marked?
Show Hint
For independent probability questions, simplify each individual fraction first (e.g., \( 40/200 = 1/5 \) and \( 50/300 = 1/6 \)) before multiplying. This keeps the calculations simple and prevents arithmetic errors.
