Data::RandomPerson::Choice - Select an element from a list in proportion This document refers to version 0.4 of Data::RandomPerson::Choice, released Sept 13th, 2005 use Data::RandomPerson::Choice; my $c = Data::RandomPerson::Choice->new(); $c->add( 'this' ); $c->add( 'that', 11 ); # The list now contains 12 elements, 1 'this' and 11 'that'. A random # element will be selected with the following probablilty: # # this = 1/12 = 0.083 # that = 11/12 = 0.917 print $c->pick();

Overview
A way of simply defining the probablity of a selection of values based on the ratio of the elements this add( 'this' ) adds one element to the list, the count argument of add defaults to 1. add( 'that', 11 ) adds another 11 elements to the list giving a total of 12. The chance of picking 'this' is 1 in 12 and the change for 'that' is 11 in 12. You can add as many values as you like to the list.

Constructors and initialization
Returns a Data::RandomPerson::Choice object.
