- 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 list1 = {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 list1 = {2, 3, 3, 4, 5}.
Hint: In the 
CAS View the input list can contain different types of objects:
- Examples:
Sample[{-5, 2, a, 7, c}, 3]yields for example {a, 7, -5}.- 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}.
