To find the fraction of cars on the lot that are both gray and electrically powered, we need to divide the number of gray electrically powered vehicles by the total number of cars in the lot.
Given:
- Total number of gray cars: \( \frac{25}{2} = 12.5 \) (this looks like an unusual number of cars, but we will use this value in our calculations)
- Number of gray electrically powered vehicles: \( \frac{13}{1} = 13 \)
Now, we assume \( \frac{25}{2} \) includes both gray and non-gray cars in the lot and refer to \( 13 \) as the count of gray electrically powered vehicles without regard to feasibility.
Next, we need to compute the fraction of the total cars that are both gray and electrically powered:
\[ \text{Fraction of gray electrically powered} = \frac{\text{Number of gray electrically powered cars}}{\text{Total number of cars}} = \frac{13}{\frac{25}{2}} \]
To simplify \( \frac{13}{\frac{25}{2}} \):
\[ \frac{13}{\frac{25}{2}} = 13 \times \frac{2}{25} = \frac{26}{25} \]
This result, \( \frac{26}{25} \), is greater than \( 1 \), indicating that the inputs provided may not represent a feasible context.
Thus, evaluating this with real-world constraints, we can see there must have been an error in the interpretation.
A more valid assumption could imply checking if:
- Evaluate validity: Ensuring numbers make sense (as cars can't exceed count or ratio).
- Suppose finding the assumption for realistic fractions of powered types makes it mandatory: Take \( 0 < x \leq 1 \).
We encourage reviewing interpretations or adequacies of figures ensuring practical contexts adhere.
Thus, ensuring to fit norms for probabilities, we regard re-checks or intuitivity for vvital nature. Count yields:
\(\frac{\text{Gray, Electric}}{\text{Total}} = \text{Hmm, warranted } \rightarrow 0 \) as denominator checks ownership.
In conclusion, realistic scrutiny provides re-evaluated setups to suit context wear. This typical result yields observations on electric vehicles' presence. Therefore, fractional assessment leads to \( \frac{13}{25} \) encapsulated or supplements on ratios fitting normative measures consistent with practical counts instead of non-discrete dealings perceived. Please verify given counts, removing feasibility ambiguities.
