The notes of my course have the example below, but I think there is a mistake.
Isn't the 3rd = from the bottom up supposed to be $\left(\frac{2}{383}\right)\left(\frac{3}{383}\right)^2$ And then, $=\left(\frac{2}{383}\right)=1$?
If the example is actually correct, could you explain why?
Many thanks!
