This is a test page

I'm going to write some math

$E(|A\cap B|)=n*P(i\in A\cap B)=n*\left({\frac {\binom {N-1}{n-1}}{\binom {N}{n}}}\right)^{2}={\frac {n^{3}}{N^{2}}}$

I hope that works

Final Answer:
The final solution is the portion of the graph that below $y=\vert x\vert +1$ and inside $x^{2}+y^{2}=9$
