Answer 1

The correct option is D 17

Let us arrange the given data in a table in ascending order we get,
0, 0, 0, 0, 1, 1, 2, 2, 3, 3, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10
Marks which are more than or equal 5 are 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10.
So, there are 17 students whose marks are greater than or equal to 5 .
Hence option D is correct.
