Explanation / Answer

1.Yes it is a set that is not well defined

6. n(a) means number of elements in A => n(A) = 5

5.False because both sets don't have all the elements same.

the right hand side set has one element extra.

4.Here we need to tell about cars that are owned by students

hence option A

3.Here the set has to have elements greater than -2 and less than 2

=> it doesn't include -2 and 2

{ -1 , 0 , 1 }

2. it is a finite set

because it has only 6 elements {2, 3, 4, 5, 6, 7, 8}
