Answer:
The likelihood of her remembering an actual event is very slim
Step-by-step explanation:
Due to the fact that Tom recalls the incident his 8 year old daughter is trying to relay to him happened in a cartoon, it is unlikely it happened for real.
The 8 year old is telling her father Tom, that her toy was ran over by a car in an event that happened years ago. Her father remembers that was a scene from a cartoon so it is very likely that what the 8 year old thinks was a real event was in fact her recalling the cartoon and interpreting that it happened to her.
An 8 year old's brain isn't fully developed to differentiate reality and fantasy and as such, such occurrences are not rare.
