commutativity degree of certain finite ac-groups

For a finite group g, the probability of two elements of g that commute is the commutativity degree of g denoted by p(g). as a matter of fact, if c = {(a; b) ∈ g×g | ab = ba}, then p(g) = |c|/|g|2 . in this paper, we are going to find few formulas for p(g) independent of  |c|; for some acgroups, and also in some special cases of finite minimal nonabelian groups. moreover, the study will present implications for certain qualified finite groups.
