What is the probability of getting a triangle with sides of the following lengths?
The lengths are: 2 cm, 3 cm, 5 cm for one triangle and then the other triangle's are 7 cm, 11 cm, 13 cm.
If you know the answer can you also show me how to do it?
this is exactly what my teacher gave us for our Problem of the Week. so, it has to do with probability.

the probability of getting a triangle with 2, 3, and 5, is zero.
the probability of getting a triangle with 7, 11, and 13, is 100%
To get a triangle, 2 sides added together must be greater than the 3rd side.
In the first one 2 + 3 = 5....the other side is 5, so they would not form a triangle.

Q1) the probability of a triangle of 2 3 5 is 0, these measure will make a straight line
Q2) not sure what you mean as to "the probability" of getting a certain triangle
considering triangle can be of any measure from .000001cm to 100,000,000 km and beyond???
so what is the probability of any given set of measurements of a triangle, infinity, i suppose??

okay,..this has nothign to do with probability unless u are given like sticks to pick out and make triangles with those....unless it was a right angled triangle then u cant have the first triangle or second.
