In a class of 40 students, 25 own a bicycle, 17 own a car, and 4 own neither a bicycle nor a car. how many of the students own both a bicycle and a car

6 students own a bicycle and a car because 25+4+17 = 46 which mean 6 have both

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!
