Answer with Step-by-step explanation:
We are given that
Total dogs=24
Total cats=18
Total animals=24+18=42
Male dogs=8
Male cats=6
Total male animals=8+6=14
Total female animals=42-14=28
Female cats=18-6=12
Dogs female=24-8=16
a.We have to find the probability that the pet is male, given that it is cat.
It means we have to find P(Male/cat)
Conditional probability: ![P(A/B)=\frac{P(A\cap B)}{P(B)}](https://tex.z-dn.net/?f=P%28A%2FB%29%3D%5Cfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D)
P(Cat)=![\frac{18}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B42%7D)
![P(male cat)=\frac{6}{42}](https://tex.z-dn.net/?f=P%28male%20cat%29%3D%5Cfrac%7B6%7D%7B42%7D)
![P(Male/cat)=\frac{\frac{6}{42}}{\frac{18}{42}}](https://tex.z-dn.net/?f=P%28Male%2Fcat%29%3D%5Cfrac%7B%5Cfrac%7B6%7D%7B42%7D%7D%7B%5Cfrac%7B18%7D%7B42%7D%7D)
P(male/cat)=![\frac{6}{18}=0.33](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B18%7D%3D0.33)
b.![P(female cat)=\frac{12}{42}](https://tex.z-dn.net/?f=P%28female%20cat%29%3D%5Cfrac%7B12%7D%7B42%7D)
![P(female)=\frac{28}{42}](https://tex.z-dn.net/?f=P%28female%29%3D%5Cfrac%7B28%7D%7B42%7D)
![P(Cat/Female)=\frac{\frac{12}{42}}{\frac{28}{42}}=\frac{12}{28}=0.43](https://tex.z-dn.net/?f=P%28Cat%2FFemale%29%3D%5Cfrac%7B%5Cfrac%7B12%7D%7B42%7D%7D%7B%5Cfrac%7B28%7D%7B42%7D%7D%3D%5Cfrac%7B12%7D%7B28%7D%3D0.43)
c.P(Dog)=![\frac{24}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B42%7D)
![P(dog female)=\frac{16}{42}](https://tex.z-dn.net/?f=P%28dog%20female%29%3D%5Cfrac%7B16%7D%7B42%7D)
![P(female/dog)=\frac{\frac{16}{42}}{\frac{24}{42}}](https://tex.z-dn.net/?f=P%28female%2Fdog%29%3D%5Cfrac%7B%5Cfrac%7B16%7D%7B42%7D%7D%7B%5Cfrac%7B24%7D%7B42%7D%7D)
![P(female/dog)=\frac{16}{24}=0.67](https://tex.z-dn.net/?f=P%28female%2Fdog%29%3D%5Cfrac%7B16%7D%7B24%7D%3D0.67)
