Best ResponseYou've already chosen the best response.0not sure what you mean. i meant use the second proof in the paper i sent you. not the volume one, but the line segment one.

Best ResponseYou've already chosen the best response.0i may be easier to do this in chat, or quicker, but i can write the idea of the proof here. i am just mimicking the proof i sent you in the pfd .

Best ResponseYou've already chosen the best response.0you have a "rod" stick whatever and you are going to break it into 4 parts by picking 3 points uniformly at random, and the question is what is the probability that you can make a quadrilateral

Best ResponseYou've already chosen the best response.0you already know the answer is 1/2 so far correct. so we just need the proof

Best ResponseYou've already chosen the best response.0first trick to to say that the rod has length one so we can dispense with ratios

Best ResponseYou've already chosen the best response.0so it looks something like this 0 abc1 where a, b, c are the points chosen at random to break up the rod

Best ResponseYou've already chosen the best response.0now the question is "when would you not get a quadrilateral\"

Best ResponseYou've already chosen the best response.0construction of a quadtrilateral will be impossible if \[\overline{0a}\] is bigger than one half, i.e. if all three points are to the right of the midpoint of the segment. the probability that one is to the right is 1/2 and all three to the right would be \[(\frac{1}{2})^3\]

Best ResponseYou've already chosen the best response.0the same is true for the other three segments, and the probability that each of them is bigger than one half is also 1/8 so the probability of failure is 4 times 1/8 = 1/2 and therefore so is the probability of success.
