is anyone know how to display formular in wikipedia ?

Question

in firefox, the label is " :1-\left(1-\frac{1}{m}\right)^{kn}. ", i think there should be one add-on to parse the formular to give right display. thank you.

Answer 1

If this appears, you either have displaying of pictures disabled or some configs are set in the wrong way (Those of your wiki* account).

But man, this question is really off-topic.

Answer 2

This is what You want ?
