Um....
This is the Venn diagram
We know that 25 own a bicycle
17 own a car
4 own neither a bicycle nor a car
In coclude, there 21 own a bicycle not a carm 13 own only car. Add upp together to get 34. Then, subtract 40 with 34 to get 6. As a resultm there are 6 students who both own a bicycle and a car. Hope it help!
