Let Formula: see text be a finite commutative ring. In this paper, we consider the probability that the product of randomly chosen three elements of Formula: see text is zero, which we denote by Formula: see text. First we obtain bounds for Formula: see text for various classes of rings and then show that for any ring Formula: see text with identity Formula: see text. Finally, we characterize all commutative rings Formula: see text with identity with certain range of Formula: see text.
