Could a reasonable person have foreseen the plaintiff's injury?
If a risk is reasonably foreseeable, does one have a duty to prevent it?
It is not enough that the event should be such as can reasonably be foreseen; the further result that injury is likely to follow must also be such as a reasonable man would contemplate, before he can be convicted of actionable negligence.
The remote possibility of an injury occurring is not enough; there must be sufficient probability to lead a reasonable man to anticipate it.
