Factorial, Biomial coefficient, and Pascal's triangle
The number
,
called
factorial,
is the product of
with all of the positive integers less than
.
The first few factorials

The
binomial coefficient
,
pronounced

,
is the
quotient
and
counts the number of ways to pick
things from
things. The binomial coefficient gets it name from the fact
that
The
binomial coefficients can be generated using Pascal's
triangle
where
each row begins and ends with
,
and each number in between is the sum of the two numbers above it.
