 Ans :3

 Exp :The MEAN function adds all of the non-missing values and divides by the number of non-missing values. In this case, 6 + 4 + 2 divided by 3 is 4.

 You can learn about the MEAN function in Transforming Data with SAS Functions.

 All non-missing divided by the sum of the number of non-missing (equivalent to completely ignore missing)
