1. The bar graph shows the number of students who prefer different types of pets: dogs, cats, birds, and fish.
2. For dogs, 30 students prefer them (blue bar) and 25 prefer them as a second choice (orange bar).
3. For cats, 20 students prefer them (blue bar) and 25 prefer them as a second choice (orange bar).
4. For birds, 40 students prefer them (blue bar) and 35 prefer them as a second choice (orange bar).
5. For fish, 15 students prefer them (blue bar) and 10 prefer them as a second choice (orange bar).
6. Birds are the most preferred pet overall with 75 total preferences (40 + 35).
7. Fish are the least preferred pet overall with 25 total preferences (15 + 10).
8. The difference in preference between birds and fish is 50 (75 - 25).
9. Cats and dogs have the same number of second-choice preferences (25 each).
10. The total number of student preferences across all pets is 180 (30+25+20+25+40+35+15+10).
