Final answer:
Tony is unlikely to succeed in the negligence lawsuit as there is typically no duty to rescue in this type of situation.
Step-by-step explanation:
Tony is unlikely to succeed in the negligence lawsuit as there is typically no duty to rescue in this type of situation. Negligence occurs when someone fails to exercise the level of care that a reasonable person would in a similar situation. In general, individuals are not legally obligated to assist someone in danger, unless they have a pre-existing duty of care, such as a lifeguard or a medical professional. Since Katrina did not have a duty of care towards Tony, she cannot be held legally accountable for not saving him.
