Damn! I am wrong! And a guy with the name of a defeat pointed my mistake! (I am French)
So, what I have just established is that the probability is less than 50%.
L = length of the stick.
If the first point is in the first half, at x between 0 L and 0.5 L, to be able to have a triangle, the second point need to be between 0.5 L and (0.5 + x) L.
I have the feeling that we need to integrate a function, but I an too old and tired for that.
Unless the job is somehow related to snapping sticks or figuring out arcane algorithms, it doesn't fucking matter.
Unfortunately, as a software developer, I sometimes have to figure out arcane algorithms…
took me a long time to get it
it's not an easy question
i can't remember the reasoning, but i remember the answer
you don't need calculus for it, but I'm sure if it's strong enough it can help
you can just reasoning it out in your mind, but it's not easy
i don't want to attempt it again
I cheated and found the answer googling "stick 3 part triangle" :
https://www.quora.com/A-rod-is-broken-into-three-parts-what-is-the-probability-that-the-three-parts-can-be-arranged-to-form-a-triangle
The answer is: 25%
haha yes it is :)
took me a long time thinking it over to get it right
