i read a book and it proves like that

average velocity=[itex]\int vf(v) dv[/itex]

I don't understand why we don't have to divide it by N because we should be calculating the average,but not the total.

Would anyone tell me where i went wrong

by multiplying each bin of the velocities, you already normalize the velocity distribution
