Answer:
8
Step-by-step explanation:
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Given:
- number of convertibles = 4
- total number of vehicles = 30 + 4 = 34
[tex]\implies \sf P(convertible)=\dfrac{4}{34}=\dfrac{2}{17}[/tex]
To find the expected number of convertibles from the first 68 vehicles:
[tex]\begin{aligned}\implies \sf P(convertible) \times 68 & =\sf\dfrac{2}{17} \times 68\\\\ & = \sf8\end{aligned}[/tex]
Answer:
30 other vehicles + 4 convertibles = 34 cars
34 * 2 = 68
30 * 2 other vehicles + 4 * 2 convertibles = 68 cars
60 other vehicles and 8 convertibles
