What does 20% chance of rain really mean?
In: Other
This is actually misinterpreted quite often. When you are given a chance of rain in an area, the probability that it will rain in at least some part of that area is close to 100%. So what the chance of rain actually tells us is the percentage of the area within that region that will receive rain (with some assumptions going into it).
As an example, if the weather report says there’s a 20% chance that it will rain in town A, then 20% of the area in town A will receive rain and the probability that at least some part of town A receives rain is about 100%
