II Statistics Topic Notes - typo?

https://maths.org/step/sites/maths.org.step/files/s2s3/Statistics_topic_...

At the bottom of page 3. I believe that $ \lamda $ should used for both the mean and variance - and the standard deviation is its square root. The notes show $ \lamda^2 $ being the variance.

(Am I doing something wrong? Wherre's my LaTeX lamda?)

$\lambda$

I have problems with typing lambda as well. It is very annoying when your latex won't compile because of a typo!

Yep! Found it. (I was confused for a while as I was looking at page 2 where the variance is given as $\lambda$). Will sort it out now.

Thanks for pointing it out!

Haha yeah I would say I pride myself on my spelling and grammar but after spending 20 mins wondering what was wrong with MathJax and giving up in the end I start to doubt myself.
$\lambda \lambda \lambda \lambda \lambda \lambda \lambda \lambda $
