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?

 

I know this was answered already but these are diff numbers

 

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 :)

How about you give the addresses of the previous questions/answers.

 

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

 

If you do not understand an answer you should quiz the answerer on the original thread.

 

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%
