Next year's edition will be updated to ask what are the chances there will be a 500 year flood in the next 6 months.
A) 97%
B) 98%
C) 99%
D) 100%

63%
1-((99/100)^100)= .634
1-((99/100)^100)= .634

It's gonna be something like the % of one not occurring is .99. And that to the ^ 100 power is whatever and 1 minus that.

Oh. Duh. Thanks.

What is the percent probability of a flood with a 100 year frequency occuring within 100 years?
.99^100 would be the probability of it NOT occurring... which rounds to 37%.
100% - 37% = 63% chance that it does happen.

This is the answer, although I think saying a certain flood has a 1 percent chance of happening each year and the same flood occurs every 100 years are two different statements.

Surprise surprise!!! The lawyer sucks at math, and probably most real life skills by extension. Does your wife change flat tires for you?

If its "within" 100 years or 99.999 years its with 99% certainty.
If its 100 years period. It's 100% or 1 every 100 years.
Ahh shite LucasP nice!
Is that P distribution?

Very different.
The chance a houston flood or shreveport flood happens next year is the same, even though they both happened within the last two years

B) 63.3%
It's a binomial distribution with 100 chances, the probability of success being 1%, and the successes >0.

1-(0.99)^100= 63%

What are the chances of a 100-year flood happening more than once in a decade?
