Answer: He is more likely to lose the case.
Step-by-step explanation:
Philip is likely to lose because eventhoug the mechanic's action or conduct was an act of negligence toward Marsha, it was not a proximate causation in relation to Phillip, who was far away.
Proximate causation means it was not the primary cause of his injury , the mechanic could have not predicted or foreseen that Philip was going to be injured buy a running dog and that frees him from a duty to Philip.
