Sample[ <List L>, <Size n> ]
Returns list of n randomly chosen elements of L; elements can be chosen more times.
Sample[ <List L>, <Size n>, <Boolean for replacement> ]
Returns list of n randomly chosen elements of L. Elements can be chosen more times if and only if the last parameter is true.
Example: Sample[{1, 2, 3, 4, 5}, 5, true] yields for example {2,3,3,4,5}.


CAS Syntax

Sample[ <List L>, <Size n> ]
Returns list of n randomly chosen elements of L; elements can be chosen more times.
Sample[ <List L>, <Size n>, <Boolean for replacement> ]
Returns list of n randomly chosen elements of L. Elements can be chosen more times if and only if the last parameter is true.
Example: The list can include lists as well: Let List1 be {1,2,3}. Sample[{List1,4,5,6,7,8}, 3, false] yields for example {6,{1,2,3},4}.
