Pascal’s Triangle is the triangular arrangement of numbers which gives the coefficients in the expansion of any binomial expression. Visit BYJU'S to learn Pascal's triangle formula, properties and many solved examples.
0≤k≤a+b, 总共可能的情况为:从A拿0个B拿k个 + 从A拿1个B拿k−1个 + 从A拿2个B拿k−2个 + ... +从A拿k−1个B拿1个 + 从A拿k个B拿0个,化简就是(a+bk)=Σs=0k(as)(bk−s),这个也叫Chu-Vandermount formula或者Committee selection identity....
Pascal's triangle is used to compute binomial probabilities, which occur when a scenario has exactly 2 possible outcomes that are both equally likely. It can also be used to identify combinations of any two numbers. What is Pascal's triangle formula? Pascal's triangle formula is (n+1)C(r...

So Pascal's Triangle could also be an "n choose k" triangle like this one.(Note that the top row is row zero and also the leftmost column is zero)Example: Row 4, term 2 in Pascal's Triangle is "6" ... ... let's see if the formula works: (42) = 4!2!(4−2)! = 4!
(Mathematics) a triangle consisting of rows of numbers; the apex is 1 and each row starts and ends with 1, other numbers being obtained by adding together the two numbers on either side in the row above: used to calculate probabilities ...
Pascal's triangle 1 Pascal's triangle In mathematics, Pascal's triangle is a triangular array of the binomial coefficients in a triangle. It is named after the French mathematician, Blaise Pascal. It is known as Pascal's triangle in much of the Western world, although other mathematicians ...

In defining L1, we consider a point P at (x, y) inside the triangular element, as shown in Figure 7.6, and form a sub-triangle of 2–3–P. The area of this sub-triangle is noted as A1, and it can be calculated using the formula Sign in to download full-size image Figure 7.6....
