Answer 1

Yes, your result is correct.
According to the task, you always get 2 dollars, regardless of the houses visited.
So the chance of getting a dollar at any house is:
2 / houses * 100 percent
You also did correctly to use a double , and Math.ceil for rounding up, and finally converting back to int.
