If poolsize is not specified, the size of the pool is equal to the number of items listed in the items attribute.
When setting poolsize in combination with itemprobabilities, choose a size for which each of specified probabilities results in a whole number of items in the pool. If the poolsize results in a fractional count of a given item, the count will be rounded to the nearest integer.
The following list creates a random selection pool of size 100 consisting of 30 "X and 70 "O".
/ items=["X"; "O";]
/ itemprobabilities=[0.3; 0.7;]
The following list creates a random selection pool of size 10 consisting of 5 "A" and 5 "B":
/ items=["A"; "B";]
The following list creates a sequential selection pool of size 9 equivalent to /items = [1; 2; 3; 1; 2; 3; 1; 2; 3;]:
/ items=[1; 2; 3;]
