Hi brinckma,

In these types of questions, it's important to note that the mouse can only go "down" - it can't go in "circles", go up, double back, etc.

With that 'restriction' in place, each "junction" on the map gives the mouse 2 options (go left or go right). The first junction is at the top and the mouse will cross 3 additional junctions along the way to the bottom.

2^4 = 16 paths

GMAT assassins aren't born, they're made,
