Answer:

The probability is  [tex]P(4 \ doors | sunroof ) = 0.40[/tex]

Step-by-step explanation:

 From the question we are told that

        The number of cars packed is  [tex]n = 100[/tex]

The objective of this solution is to find the probability that the car which has a sunroof also has four doors

   This probability is mathematically represented as

               [tex]P(4 \ doors | sunroof )[/tex]

Baye's Rule define this probability mathematically  as

             [tex]P(4 \ doors | sunroof ) = \frac{P(4 \ doors \ n \ sunroof )}{P(sunroof)}[/tex]

   From the diagram

          [tex]P(4 \ doors \ n \ sunroof ) = 20[/tex]

and     [tex]P(sunroof) = 50[/tex]

So

      [tex]P(4 \ doors | sunroof ) = \frac{20}{50}[/tex]

      [tex]P(4 \ doors | sunroof ) = 0.40[/tex]
