Description:

Returns a random integer between 1 and total such that the probability of each number is proportional to itself. For example, 2 is twice as likely as 1, and 3 is 3 times as likely as 1. This may be useful for ordinally weighted lotteries, where applicants have a number of lottery tickets determined by some ranking. For example, you might want to randomly award a scholarship, but you might also want individuals with greater financial need to be more likely to receive the scholarship.
