I'm going to write some math

Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 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
