RandomElement( <List> )
Returns randomly chosen element from the list (with uniform probability). All elements in the list must be of the same type.
Example:
RandomElement({3, 2, -4, 7}) yields one of {-4, 2, 3, 7}.


Note Hint: In the Menu view cas.svg CAS View this command also works with symbolic input.
Example:
RandomElement({a,b,c,d}) yields one of {a, b, c, d}.
