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 2 units?

thanks

if this question's already been answered, you can learn from the method they used and plug in the new numbers you have.

if you're still confused, i can give this problem a shot :)

there is no point in me giving the same/similar answer as before if you did not understand the first time.

You can make a new post directing people to the original and you can ask for it to be unlocked if it is locked.

Use a contour probability map to solve.

Area of little (desirable ) triangle = 0.5

Area of large (sample space) triangle = 0.5*5*5 = 12.5

probability of  that the yare all less than 2 units =  0.5 / 12.5  = 5/125  = 1/25   or  0.04   or  4%
