Sharlene has just put a down payment on a lot in a small subdivision. There are 18 lots in the subdivision, and all are approximately 0.35 acres in size. Three builders have been contracted by the subdivision manager to each build six homes in order to finish the subdivision in 6 months. Sharlene's uncle is one of the builders contracted by the subdivision manager. What is the probability that Sharlene's uncle will be the builder that builds her house? Round your answer to two decimal places, if necessary.
