if you have a random line generator that produces lines uniformly between 0 and 1 units in length, then what is the probability of any given line produced having length greater than 0.5?

if you have a random square generator that produces squares uniformly between 0 and 1 units of area, then what is the probability of any given square produced having area greater than 0.25?

if you have a random cube generator that produces cubes uniformly between 0 and 1 units of volume, then what is the probability of any given cube produced having volume greater than 0.125?

hurry up /sci/, don't let /sp/ beat you

it's also okay to admit that you are not smart enough to figure it out and attempting to figure it out would encourage the growth of brain tumors

Because being patronizing is the best way to convince someone to do your homework.

haha jokes on you it's not solvable

>> No.5578850

if i understood correctly and it's an uniform distribution
0,5
0,75
0
why wouldn't it be solvable?

Come on guys. /sp/ got it almost instantly, are you guys that dumb?

I think that is the best answer, imo. But it's an official paradox of probability theory as to why it isn't .5, .75, .875 respectively.

>> No.5578892

>>5578881
They clearly state that the length, area, and volume are uniformly distributed in their respective problems. The answer would be 0.5 for all if the lengths were uniformly distributed between 0 and 1.

>> No.5578895

>>5578881
why wouldn't it be .5, .75, and .875? where is the paradox?

>> No.5578910

>>5578892
>>5578895

It comes from the denseness of the real numbers.

it would be closer to .5, .75, and .875 if the squaring/cubing of the lines "missed" some values of area/volume -- But it does NOT miss any values.

Welp, i don't get it.
Pic related. I'm sorry if i'm retarded, i hardly studied any statistics. I guess the problem is that the units below aren't cm^3?
