queries can occur at any time and experienced individuals can only sort out those issue such as online signature. Institutions like airslate.com/product/analytics has set up a question answer seminar every week. This will eliminate any kind of doubts in pupils mind regarding this matter.

Take n = 3 and (i1,i2,i3) = (5,6,7)

5,6,7: i1*i2 + i2*i3 + i3*i1 = 30 + 42 + 35

5,7,6: i1*i2 + i2*i3 + i3*i1 = 35 + 42 + 30

6,5,7: i1*i2 + i2*i3 + i3*i1 = 30 + 35 + 42


etc ...

They are all the same so divide by n! to get the average.
