Maybe the correct formula is ∫f(x)dx≈(1/N)*∑f(r)/p(r)
?
This is definitely a typo. From the wikipedia artice on Monte Carlo integration the correct formula should be:
$$ \int f(x) dx \approx \frac 1 N \sum_{i=0}^{N-1} \frac {f(x_i)} {p(x_i)} $$

In book3-6.1Returning to the Cornell Box:
Remember Monte Carlo basics: ∫f(x)≈∑f(r)/p(r) ...
, Shouldn't the correct formula be∫f(x)≈(1/N)*∑f(r)/p(r)
?
