Question

If geologists calculate that the recurrence interval of a flood of a certain size is 100 years, then...

a) such a flood happens every 100
years.
b) the probability that such a
flood will happen next year is
1%
c) if such a flood happened last
year, another is less likely to
occur than if it happened 20
years ago.
d) it is possible for even larger
floods to have a shorter
recurrence interval

Answer 1

Geologists calculate the recurrence interval of a flood to estimate the probability of a flood of a certain size occurring in any given year.

Step-by-step explanation:

The correct option would be b) No, if geologists calculate that the recurrence interval of a flood of a certain size is 100 years, it does not mean that the flood happens every 100 years. The probability that such a flood will happen next year is 1%.
