A stick has a length of $5$ units. The stick is then broken at two points, chosen at random. What is the probability that all three resulting pieces are shorter than $3$ units?
It says it's wrong...
MaxWong answered this question on the link provided, and according to him, the answer is \(13 \over 50\)
Here is the answer: https://web2.0calc.com/questions/probability_11169#r1

Yes it is 13/25 (Max I think you made a small error)
Here is my contour probability graph
And here is the pic
The purple area of 6.5 units^2 contains all the favourable outcomes
and the the blue (with purple) area of 12.5 units^2 conatins all possible outcomes.
6.5/12.5 = 0.52 = 13/25
