Sample[ <List L>, <Size n> ]
Returns list of n randomly chosen elements of L; elements can be chosen several times.
範例:
Sample[{1, 2, 3, 4, 5}, 5] yields for example {1, 2, 1, 5, 4}.
Sample[ <List L>, <Size n>, <Boolean for replacement> ]
Returns list of n randomly chosen elements of L. Elements can be chosen several times if and only if the last parameter is true.
範例:
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 several times.
範例:
Sample[{-5, 2, a, 7, c}, 3] yields for example {a, 7, -5}.
Sample[ <List L>, <Size n>, <Boolean for replacement> ]
Returns list of n randomly chosen elements of L. Elements can be chosen several times if and only if the last parameter is true.
範例:
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}.
