Estimate the number of Lyft rides on Halloween.

To estimate Lyft rides on Halloween, I would start by considering the US population and then segmenting it based on age groups likely to participate in Halloween activities (e.g., 18-40). I'd then estimate the percentage of this demographic that uses ridesharing services and, specifically, Lyft. Further refinement would involve estimating the proportion of these users who would take a Lyft to and from Halloween-related events, accounting for factors like event attendance, alternative transportation, and typical ride frequency for such occasions.
