by hand:
How many paths are there from the point (0,0) to the point (10,20) in the plane such that each step either consists of going one unit up or one unit to the right? Explain your answer. If your answer contains large powers or binomial coefficients, there is no need to calculate them.

A robot is standing at the origin (0,0) of a square grid. The robot is programmed to move exactly one unit at a time, in one of three directions: up, down, and right. The robot will never move left. For example, starting at (0,0), the robot will move either • one unit up, to (0,1), one unit down, to (0,-1), or • one unit right, to (1,0). . The robot is programmed to make exactly 5 moves, and then stop....

1) Consider an ant that is walking on a Cartesian grid, starting at (0,0) and ending at (15, 18). The ant always chooses to walk exactly one unit either up or to the right (towards his destination) whenever he arrives at a Lattice point. (A Lattice point is a point with integer coordinates.) Thus, from (0,0) he either walks to (1,0 or (0). If the ant is not allowed to go to the points (6, 8) and (, 15), how...

Consider an ant that is walking on a Cartesian grid, starting at (0,0) and ending at (20, 12). The ant always chooses to walk exactly one unit either up or to the right (towards his destination) whenever he arrives at a Lattice point. (A Lattice point is a point with integer coordinates.) Thus, from (0,0) he either walks to (1, 0) or (0, 1). If the ant is not allowed to go to the points (10, 5) and (12, 8),...

An ant starts from the original of a 2-D grid, at the point (0,0). Then each time it moves either i) right by one unit distance, e.g., from (0,0) to (1,0), ii) up by one unit distance, e.g., from (0,0) to (0,1), or iii) stay still with probabilities 0.3, 0.2, and 0.5, respectively. After 10 moves, what is the probability that the ant settles down at point (2,5)?

Help with Pascal’s Triangle: Paths and Binary
Strings
Suppose you want to create a path between each number on Pascal's Triangle. For this exercise, suppose the only moves allowed are to go down one row either to the left or to the right. We will code the path by using bit strings. In particular, a O will be used for each move downward to the left, and a 1 for each move downward to the right. So, for example, consider...
