It seems like the code output always has a same birthday with person 1-10. Is there a reason why? It seems too often that a shared birthday has a person 1-10 and then some other person. eg person 2 and person 88 share a birthday.
Are there months and days birthdays are more likely to occur, or are we assuming every day of the year has an equal chance of being someone’s birthday? Maybe I have a misunderstanding of probability or the simulate.py code but an 89% probability of two people sharing a birthday in a group of 40 people seems really high unless some days are weighted heavier than others.
I am a total beginner with no previous coding experience. Curiously, I opened the pycache folder, inspected the simulate.py file (which I believe contained the whole code), and noticed that “num_people_in_room = 2” in line 5 of script.py does not appear anywhere in simulate.py (although it seems to be defined in lines 33 and 35 of simulate.py file). How then are the two files (script.py and simulate.py) related or is there no link? Sorry for the seemingly dumb question, I just want to understand the coding context!
@augustkade6693427971 I agree. My probability for 30 people was 70.63% which seems really high as well. Although I don’t know for sure, I’m sure the random quality (there’s a different word for it than ‘quality’) is truly random. I highly doubt the organization would give us an example like that if it truly wasn’t random. But probability is funny when you think about it without doing the math, which is why Vegas always wins.
