A system and method for selecting a resource from among a plurality of resources. A total range of numbers is divided into a plurality of sub-ranges, each associated with a respective one of the resources. An indexing number, e.g., a random number, is generated and, when it falls within the total range of numbers, the resource associated with the sub-range into which the indexing number falls is selected. When the indexing number falls outside of the total range, a resource associated with the difference between the indexing number and the greatest number in the total range is selected.
