Use randSamp(list,1 (or however many items you want)) where list is a list of anything. randSamp should be supported on any Nspire, not just CAS models.

However you want; you can use a literal, like {1,2,5}, or a function, like seq(2x+1,x,1,10). Any valid list will work.

In basic:

list := {1,8,9,2,5,7}
number := randSamp(list,1)

In lua:

list = {1,8,9,2,5,7}
number = list[math.random(1,table.getn(list))]
