Webprobability theory is given by eq. (5). We have therefore verified the inclusion-exclusion principle. There are numerous applications of the inclusion-exclusion principle, both in set the-ory and in probability theory. In particular, it provides a powerful tool for certain types of counting problems. WebOne can also prove the binomial theorem by induction on nusing Pascal’s identity. The binomial theorem is a useful fact. For example, we can use the binomial theorem with x= 1 and y= 1 to obtain 0 = (1 1)n = Xn k=0 ( 1)k n k = n 0 n 1 + n 2 + ( 1)n n n : Thus, the even binomial coe cients add up to the odd coe cients for n 1.
