SUMMARY
The discussion centers on calculating the parameter p of a geometric distribution given a mean of 0.6. The probability generating function (p.g.f.) is defined as $$q/(1-ps)$$, where $$q$$ is (1 - p) and $$s$$ is a dummy variable. To find p, the relationship between the mean and p is established as $$mean = q/p$$, leading to the equation $$0.6 = (1-p)/p$$. Solving this equation yields the specific value of p for the geometric distribution.
