Suppose that you are on the bottom left corner (green) of a 9 x 12 grid of city blocks. (a) to the top right corner (blue position (9,14)) by using only North and East moves such that you avoid the red dot (located at position (6,4))? How many different ways can you get from the bottom left corner (green position (0,0)) (b) to the top right corner (blue position (9,14)) by using only North and East moves such that you avoid both of the red X's (located at positions (6,4) and (3,10))? How many different ways can you get from the bottom left corner (green position (0,0)) (c) to the top right corner (blue position (9,14)) by using only North and East moves such that you avoid both of the purple X's (located at positions (3,4) and (5,8))? How many different ways can you get from the bottom left corner (green position (0,0))
