Answer 2

Answer:

Cardinal number: 8

Step-by-step explanation:

Cardinal number says about the number of elements in that set.

 Suppose of a set B = { x , y , z }

        Then n(B) = 3

In the same manner here,

 number of elements here = 8[ 1 , 2 , 3 , 4 , 5 , 7 , 9 , 11 ]                        

Therefore,

  n(B) = 8
