How many paths are there from point (0,0) to point (50,50) on the two-dimensional plane if each step along a path increments one coordinate and leaves the others unchanged and there is an impassable obstacle at the points (10,11) and (20, 19)? Provide a formula representation of your result that includes binomial coefficients, and navigate the reader through the development of your formula.

Question

This is a discrete math (combinatorics and discrete probability) problem. Please explain each step in detail and do not copy solutions from Chegg. 

1. How many paths are there from point (0,0) to point (50,50) on the two-dimensional plane
if each step along a path increments one coordinate and leaves the others unchanged and
there is an impassable obstacle at the points (10, 11) and (20, 19)? Provide a formula
representation of your result that includes binomial coefficients, and navigate the reader
through the development of your formula.
