# Probability and Polygons

Is there any special name in math for probability dealing with polygons?

I mean questions like: Three vertices are chosen from the seven vertices of a regular 7-sided polygon. What is the probability that they form the vertices of an isosceles triangle?

Where can I get these types of probability problems for practice?

You mean geometric probability? · 4 years ago

The specific question given is a standard probability question in a geometric setting.

The type is not Geometric Probability, which calculates probability in terms of length / area / volume.

While it could be considered as "geometric probability" where we count the number of points in which a condition is satisfied, that is not standard usage. Staff · 4 years ago

Ah yes! Thanks for the clarification. I think I missed out to read "regular". · 4 years ago

Yeah........where can I get questions in the net for practice? I'm preparing for KVPY and I've seen questions based and this in previous year question papers..... · 4 years ago
