Explanation:
See attachment for complete question
Solving (a): Tricycle, Motorcycle and Car
This is the intersection of Tricycle, Motorcycle and Car.
From the attached Venn diagram, there are 15 students in this category
Solving (b): Tricycle and Motorcycle.
This is the intersection of Tricycle and Motorcycle.
From the attached Venn diagram, we observe the following data:
![Tricycle\ and\ Motorcycle\ only =17](https://img.qammunity.org/2021/formulas/mathematics/college/rmi935go16onspmdullsxzdh65dmiwazjf.png)
![All = 15](https://img.qammunity.org/2021/formulas/mathematics/college/waxc7ahcgjcmf0668rnltsahklc0ftltm1.png)
![Tricycle\ and\ Motorcycle = All + Tricycle\ and\ Motorcycle\ only](https://img.qammunity.org/2021/formulas/mathematics/college/c3426bq1dmy7llozc3eo1mzegxh8umpb5p.png)
![Tricycle\ and\ Motorcycle = 15 + 17](https://img.qammunity.org/2021/formulas/mathematics/college/ahe500sp3q0xsqgv9smetc4p2q5g6eq8by.png)
![Tricycle\ and\ Motorcycle = 32](https://img.qammunity.org/2021/formulas/mathematics/college/xx56owoz0w6h3yxquxicqcud0oqig1dr2a.png)
Solving (c): Car and Motorcycle.
This is the intersection of Car and Motorcycle.
From the attached Venn diagram, we observe the following data:
![Car\ and\ Motorcycle\ only = 20](https://img.qammunity.org/2021/formulas/mathematics/college/s6e8tdmz8t2soywmzx3mqizh127582dzzf.png)
![All = 15](https://img.qammunity.org/2021/formulas/mathematics/college/waxc7ahcgjcmf0668rnltsahklc0ftltm1.png)
So:
![Car\ and\ Motorcycle = All + Car\ and\ Motorcycle\ only](https://img.qammunity.org/2021/formulas/mathematics/college/208gdaq49lkb3fkb9qy6dquo65prlhwdlj.png)
![Car\ and\ Motorcycle = 15 + 20](https://img.qammunity.org/2021/formulas/mathematics/college/aohbm4bdvg2n5duii6sf6onpbq6qarhldr.png)
![Car\ and\ Motorcycle = 35](https://img.qammunity.org/2021/formulas/mathematics/college/cp6v69czd55di88xnl62rbfrj69m5s82jp.png)
Solving (d): Car and Tricycle.
This is the intersection of Car and Tricycle.
From the attached Venn diagram, we observe the following data:
![Car\ and\ Tricycle\ only = 19](https://img.qammunity.org/2021/formulas/mathematics/college/nhu2hlkma7e5khpbbb4kyz5595zwlmhs7g.png)
![All = 15](https://img.qammunity.org/2021/formulas/mathematics/college/waxc7ahcgjcmf0668rnltsahklc0ftltm1.png)
So:
![Car\ and\ Tricycle = All + Car\ and\ Tricycle\ only](https://img.qammunity.org/2021/formulas/mathematics/college/rc1zuqzx4nhqddywbp57ohoxpwekxdpv79.png)
![Car\ and\ Tricycle = 15 + 19](https://img.qammunity.org/2021/formulas/mathematics/college/ukoahf42uaoupocrz50pvconbuq2elnqrn.png)
![Car\ and\ Tricycle = 34](https://img.qammunity.org/2021/formulas/mathematics/college/g9qecrobvl2g33vc571opsxcqh79vyu7yj.png)
Solving (e): Car only
From the attached Venn diagram, we observe the following data:
![Car\ only = 55](https://img.qammunity.org/2021/formulas/mathematics/college/c47lvlysjbr2vdu4xoa9r7huk346hs26z8.png)
Solving (e): Motorcycle only
From the attached Venn diagram, we observe the following data:
![Motorcycle\ only = 67](https://img.qammunity.org/2021/formulas/mathematics/college/r544l2a73eae9olgvp8m9sr9xxjpu3dsdo.png)
