What are the odds against an earthquake occuring on a certain day in a certain area if the odds of it occurring is 0.05?
5 out of 100? That means odds not occuring is 95/5 or 19/1.
I know that the odds of an earthquake over 5.5 on the Richter scale, occurring within the next second , and in San Francisco Bay Area is about 1 in 1.2 billion.
Based on the average number of larger Earthquakes reported in this area over the last 200 years.
To calculate the odds against an event occurring, we need to determine the probability of the event not happening.
In this case, the odds of an earthquake occurring in a certain area on a certain day is 0.05. To find the odds against it occurring, we subtract this probability from 1 because the sum of the probability of an event happening and the probability of it not happening is always 1.
So, the odds against an earthquake occurring can be calculated as:
Odds against = 1 - Probability of occurrence
= 1 - 0.05
= 0.95
Therefore, the odds against an earthquake occurring on a certain day in a certain area is 0.95.
