Question 1163207
One stick is 3 ft long and another is 6 ft long. You break the longer stick into  sections. 
(a) If the sections are 2 ft and 4 ft long, will the sticks form a triangle?
The longest side, 4 ft, must be longer than the difference between the lengths of the other 2 sides, and shorter than the sum of the other 2 sides.
===============================
(b) If the sections are 1 ft and 5 ft long, will the sticks form a triangle?
The longest side, 4 ft, must be longer than the difference between the lengths of the other 2 sides, and shorter than the sum of the other 2 sides.
=====================
(c) If you break the longer stick at an arbitrary point, what is the probability that they form a triangle?
