-This problem is relatively straightforward, throwing a random number sequentially and adding to the solution integer if it meets all the conditions.

 To get a guess of what to expect, we can consider if we start by rolling a 1, the solution space is forced to a regime between 0.111... and 0.10. Conversely, if we start with a 9, the solution space is more flexible, ranging from 0.999... to 0.90. Thus, with a broader solution space toward the top of the value spectrum, we expect a bias upward in comparison to just a random value over the space [0,9], which would be 4.5. After simulating many trials, we can plot the values returned and see that constrained solution space:
