Sample Command

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}.
