Biased means if the selection of every unit does not have an equal chance of being selected in a sample.
The sample is said to be good if choosing the unit is unbiased. The sample is said to be unbiased if the selection of each unit is independent.
Option A is an example of data selected in a biased way because principal chose only those student who scored the highest marks on reading test.
Options B and C are unbiased as here a selection of each number and name of the student has an equal chance of being selected.
Option D is biased because Sergio talked adults at a local fitness center where people go for maintaining their health. So, there is a chance of the selection of fitted adults more than unfitted adults.
Option E is biased because Josh met people at the dog park where dog lovers are more than a cat lover.

(3,5) I think do you have pics of ur work?
Let, consecutive number is (n-1) & n
Then: n-1+n = n+1
2n-1 = n+1
2n-n = 1+1
n = 2
& (n-1) = 2-1 = 1
So, numbers are 1 & 2
