The total number of students who own a bird as a pet in both samples is 8 + 12 = 20.
The total number of students in both samples combined is 100 + 100 = 200.
Therefore, the percentage of students who own a bird as a pet is:
(20/200) x 100% = 10%
So, 10% of students in these samples own a bird as a pet.
