I can vividly remember the worrying faces of my class mates when out further maths teacher was explaining this factor..
At first it was very difficult to comprehend using the concept of combination i.e permutation/R factorial(r!)..
But after serious researches and study i finally came across the pascal triangle which finally helped me understand the theorem.. But the major problem i have is that i dont know its application in the world of science.. Can someone with the knowledge explain better?
