You can put this solution on YOUR website! For a complete discussion see, "Mathworld Pascal Triangle"
====
Briefly the numbers in the nth row of Pascal's triangle are the
coefficients of (a+b)^(n-1)
--------
Ex: (a+b)^3 = 3C3a^3b^0 + 3C2a^2b +3C1ab^2 +3C0a^0b^3
Those coefficients are 1...3...3...1
and they are the numbers is the 4th row of Pascal's triangle.
