There are ways now to get from Andy's house to Willie's house.

Step-by-step explanation:

Given, from Dan's ranch one road is built to get to Andy's house and two roads are built to get to Willie's house.

Then, the number of ways to get from Andy's house to Willie's house =

(Number of ways to Andy's house) x (Number of ways to get Willie's house)   [Using fundamental counting principle]

= 1 x 2 = 2

Hence, there are ways now to get from Andy's house to Willie's house.
