Hello I want to calculate the $Q_1$, $Q_2$ and $Q_3$ for my Cumulative Probability Function $F(x)=\dfrac{e^x}{1+e^x}$.
So if $P=\dfrac{e^x}{1+e^x}$ how do I convert this expression to the form $x=...$ step by step? I am really bad at convertig mathematical expression I would appreciate some help.
Thanks in advance.
