Explanation:
From the question we are told that
The number of cars packed is
![n = 100](https://img.qammunity.org/2021/formulas/mathematics/college/f92q89z4joeudxwtf9sclfxwrmk5k9g6h7.png)
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
![P(4 \ doors | sunroof )](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pwpu9q6t1u8vf0e4q9wypjs3fnkmlxy6ee.png)
Baye's Rule define this probability mathematically as
![P(4 \ doors | sunroof ) = (P(4 \ doors \ n \ sunroof ))/(P(sunroof))](https://img.qammunity.org/2021/formulas/mathematics/middle-school/gi56jema0sk9orw6lx0j2gw034ihezbg17.png)
From the diagram
![P(4 \ doors \ n \ sunroof ) = 20](https://img.qammunity.org/2021/formulas/mathematics/middle-school/m8vva9iztvmhicdwe14epp0owazp2hpqcp.png)
and
![P(sunroof) = 50](https://img.qammunity.org/2021/formulas/mathematics/middle-school/k6nokgcvrz7wxbqrjqdfspos8qso6oc1xh.png)
So
![P(4 \ doors | sunroof ) = 0.40](https://img.qammunity.org/2021/formulas/mathematics/middle-school/np9n13oqig7brqg83bj6x3nmkfrusp2wj0.png)
