PASCAL'S PYRAMID AND MULTINOMIAL COEFFICIENTS!*
Hit the pause button at any time to stop the pyramid's rotation, or click once to pause and double click to continue animation.
The numbered entries in the pyramid represent the numeric results
of the expansion:
where n is the number of objects, a is the # of objects chosen first, b is the # of objects chosen from n-a and c is the number of objects left over, c=n-a-b.
We can get from one "layer" to the next using Pascal's
rule for the Pyramid:
See if you can spot these numbered entries, they should be connected!
