Returns the mode (element which occurs most
frequently) of list. If a second list, freq, is specified, it
is interpreted as the frequency of the elements in the
first list. list and freq must have the same number of
elements.

PRB
Returns the number of combinations of n items taken
r number at a time. The order in which you select the
items DOES NOT matter. items and number can be
non-negative integers or lists.
If both arguments are lists, they must have the same
number of elements. If one argument is a list and the
other a non-list, the non-list is paired with each
element in the list, and list of combinations is
returned.

PRB
Returns the number of permutations of n items taken
r number at a time. The order in which you select the
items DOES matter. items and number can be
nonnegative integers or lists.
If both arguments are lists, they must have the same
number of elements. If one argument is a list and the
other a non-list, the non-list is paired with each
element in the list, and list of permutations is
returned.
