Let 12β<1, p be a generic prime number and fβ be a random multiplicative function supported on the squarefree integers such that (fβ(p))p is an i.i.d. sequence of random variables with distribution P(f(p)=1)=β=1P(f(p)=+1). Let Fβ be the Dirichlet series of fβ. We prove a formula involving measure-preserving transformations that relates the Riemann ζ function with the Dirichlet series of Fβ, for certain values of β, and give an application. Further, we prove that the Riemann hypothesis is connected with the mean behavior of a certain weighted partial sum of fβ.
