(2) In deciding whether a reasonable person would have taken precautions against a risk of harm, the court must consider the following (among other relevant things): (a) the probability that the harm would happen if precautions were not taken; (b) the likely seriousness of the harm; (c) the burden of taking precautions to avoid the risk of harm; (d) the social utility of the activity creating the risk of harm.
