A 1-h rainfall of 10 cm magnitude at a station has a return period of 50 years. The probability that a 1-h rainfall of magnitude 10 cm or more will occur in each of two successive years is:
-
- 0.04
- 0.2
- 0.02
- 0.0004
Correct Option: D
Return period of rainfall
T = 50 years
∴ Probability of occurrence once in 50 years,
| p = | = 0.02 | |
| 50 |
Probability of occurrence in each of 2 successive year
= p² = (0.02)² = 0.004
