Sample[ <List>, <Size> ]
Returns list of n randomly chosen elements of a list; elements can be chosen several times.
Example:
Sample[{1, 2, 3, 4, 5}, 5] yields for example {1, 2, 1, 5, 4}.


Sample[ <List>, <Size>, <With Replacement> ]
Returns list of n randomly chosen elements of a list. Elements can be chosen several 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>, <Size> ]
Returns list of n randomly chosen elements of a list; elements can be chosen several times.
Example:
Sample[{-5, 2, a, 7, c}, 3] yields for example {a, 7, -5}.


Sample[ <List>, <Size>, <With Replacement> ]
Returns list of n randomly chosen elements of a list. Elements can be chosen several 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}.
