Mojave accumulates the least amount of rainfall because it's the least number you can find here. All the other numbers have two digits after the decimal point, and the first of those digits are 1 or more, but in this one, there is ONLY 1 digit, and that means that this one is the answer. Because this one is 1 digit only, but other ones HAVE another digit, which means their answer can be minimum 0.11
