10 5,040.00 10P4. 4 Combination A combination is a selection of one or more of a set of distinct objects without regard to order. The number of possible combinations, each containing n objects, that can be formed from a collection of m distinct objects is given by: mCn = (---m--------m---n-!---)--!--n---! Where m, n are integers and 69 ≥ m ≥ n ≥ 0. Use the following HP-12C to calculate the number of possible combinations.

Combination
A combination is a selection of one or more of a set of distinct objects
without regard to order. The number of possible combinations, each
containing
n
objects, that can be formed from a collection of
m
distinct
objects is given by:
Where
m
,
n
are integers and 69
m
n
0.
Use the following HP-12C to calculate the number of possible
combinations.
