How frequently do coprime pairs of integers occur?
Posted:

If I select two positive integers p and q at random, what is the probability that gcd(p,q)=1?
I've run some Excel simulations that suggests the answer is about 0.60, but am looking for a reference or methodology on how to attack this problem.
