When you add the min at the end you are adding the 2 to your range and end up with a random number from 2 to 10. If the passed argument is an integer the value will not be rounded. The math random function returns a floating point pseudo random number in the range 0 to less than 1 inclusive of 0 but not 1 with approximately uniform distribution over that range which you can then scale to your desired range.
