Is There a Logical Contrast Between a and B in the Problem of Evil?

Given the apparently gratuitous evil in the world, it is improbable that God exists. Evil for which God has no morally sufficient reason to allow. So this probabilistic version could be seen as an external challenge to Christian theism. Now before we discuss these, let me ask if there's any question of a comprehension type concerning these distinctions. Any question that you have about understanding these distinctions that you would like to ask?
