Im trying to figure out the odds of someone on hotmail having a typo and accidentally sending an email to me. In addition to that the odds of that person coming from a country i lived in before. The email went to my gmail account. The email was legit.
The population of the country 5,100,000.
Lets just say for example that gmail allows for 100 charactrrs max for an account.
Isnt this like hitting the lotto a million times in a row?
Most users have an email address that makes some sort of sense.
For example, if your email name is hotstuff001 there is every chance that there is a hotstuff002 out there and that is only one mis-typed key to accidently send you the ad on how to save 15% or more on your car insurance.
Plus the 100 characters is irrelevent as most users have probably between 5 and 10 characters in their address (just the name portion).
My email address has periods in it too ( full stops ). The email was legit and came from a country on the otherside of the planet that has a population of 5 million in it and I use to live there... I dont know man....The person that sent it and I were having a laugh.
My email address has periods in it too ( full stops )
Some email providers will alias the email automatically so full stops are optional. So, if you have the email email@example.com, you may also get emails for firstname.lastname@example.org. I suspect they'd prevent somebody from creating the email email@example.com though.
This is about the occurrence of rare events. Rare events are very common, once you think about them correctly. Imagine this situation...
"I went on holiday to the South of France, I've never been before. I went to the local marketplace and met Bob from my local pub! What are the chances of me being on holiday for the first time in France and meeting Bob!"
Sounds incredible...but it's not. What you have to ask firstly is: What are the chances of me meeting somebody I know while on holiday? I may know 100 people and we might all go on holiday twice a year. So there are already 200 chances that I meet somebody who is on holiday. The number of opportunties that any two of us meet from this group of 100 is:
100! * 20 = 1800000000000000000000000000...+ 130 more "0"s
That's 18 with 158 "0"s after it.
So the possibility that one of those opportunities arises in the same place on the same day is extremely likely indeed.
What seems incredible is that it happened to you.
An easier number to digest is this one...How many people need to be in a room for there to be a 50% chance that two of them share the same birthday?
no...23. You can use the same maths above to work it out.
