Title: Beyond Coprimality: Geometry, density, and a bijective connection

Abstract:  "What is the probability that two randomly chosen integers share no common factors?" 

This sounds like a pure number theory question. Yet, answering it takes a visual turn directly into geometry. From there, a link to squarefree integers connects probability, set theory, and bijective combinatorics, revealing a deep harmony with discrete mathematics.

 The talk is accessible, intuitive, and open to all.
