The birthday paradox

If you have 23 people in the same room there’s a 50% chance 2 of the people in the room have the same date of birth.

Mind=blown.

What kind of devil math is this?

Humans are terrible at probability.

Then again, people can't work out of a plane will take off on a treadmill and many people think mRNA vaccines change DNA so maybe humans are just retarded.

367 people makes 100% chance

70 people makes 99.9% chance

23 people makes 50% chance

Riddle me this: on your birthday you're 0 years old, and you remain 0 years old until after 1 year elapses. However, after your first birthday, you'll be 1 years old, even though you'll have lived 2 full years by your second birthday. So on your 24rd birthday, you've been alive for 24 full years, but you'll continue to call yourself 24, when really you're working on your 25th year of life. So shouldn't our age always be 1+ whatever our last birthday was?

the notion that DNA is the complete hereditary determinant is under question by several investigations. DNA polymerase, a nano-biomotor, is subjected to about 3 × 105 computational steps for every DNA base that the motor reads. Each of the internal microscopic states of the protein can store information, and these higher information storage densities cannot be stored in DNA alone. C-value paradox shows that organizational complexity is not determined by the DNA sequence, as a simple microorganism may carry larger DNA sequence than complex human. Even the form of an organism may evolve in absence of corresponding molecular evolution in DNA. Thus, the DNA is merely able to transfer the information for the shape of the proteins, not to transfer the information necessary to organize the proteins inside the cell. Experiments showed that Tetrahymena pyriformis cells and T. vorax microstomes maintain similar morphology with different proteins, while T. vorax microstomes and T. vorax macrostomes maintain different morphologies with similar proteins and the cellular configuration is not decided by the proteins they consist of. Apparently, the mechanisms behind cell (supra-cellular as well) organization and morphogenesis, thereby seem to be very difficult to describe in terms of a conventional molecular biological frame

A bat and a ball cost $1.10. The bat costs $1 more than the ball. How much is the ball?
Entire NYPD should go on strike. You'll see then how quickly the mayor changes his tone.

Basically, it is not the probably that you will have the same birthday as someone, but any 2 people have the same birthday.

So if I had a 365 sided dice that I rolled 23 times, I would have a 50% chance of rolling the same number twice.

Nope.

Nope, that'd be (1/365)^23.

You answered your own question. You are working on completing your 25th year of life but you are not yet 25.

When you are 24 you have only completed 24 years of life, so why would you call it 25?

If you want to be technical, add the months to your age. IE. 24 and 4 months old.
