\[\begin{equation} f\left(k\right) = \binom{n}{k} p^k\left(1-p\right)^{n-k} \tag{1} \end{equation}\]
See Equation (1).
Equation (2) shows how to computer mean.
\[\begin{equation} \bar{X} = \frac{\sum_{i=1}^n X_i}{n} \tag{2} \end{equation}\]
Retrieval Status Values (RSVs) for query-doocument similarities based on the BM-25 model are computed using Equation (3)
\[\begin{equation} \mbox{RSV}_{d} = \sum_{i: \, d_i = q_i = 1} \left[ \; \log \; \left( \frac{(r_i + 0.5)/(R - r_i + 0.5)}{(\mbox{df}_i - r_i + 0.5 )/ (D - R - \mbox{df}_i + r_i + 0.5)} \right) \;\cdot\; \frac{ \mbox{tf}_{i,d} + k_1 \cdot \mbox{tf}_{i,d} }{ \mbox{tf}_{i,d} + k_1 \left( (1 - b) + b \cdot \frac{\mbox{dl}} {\mbox{avg}(dl)} \right) } \; \cdot \; \frac{\mbox{tf}_{i,q} + k_2 \cdot \mbox{tf}_{i,q}} {\mbox{tf}_{i,q} + k_2} \right] \tag{3} \end{equation}\]
