Binomial expansion induction proof

WebFeb 15, 2024 · Proof 3 From the Probability Generating Function of Binomial Distribution, we have: ΠX(s) = (q + ps)n where q = 1 − p . From Expectation of Discrete Random Variable from PGF, we have: E(X) = ΠX(1) We have: Plugging in s = 1 : ΠX(1) = np(q + p) Hence the result, as q + p = 1 . Proof 4 WebTo prove this formula, let's use induction with this statement : ∀ n ∈ N H n: ( a + b) n = ∑ k = 0 n ( n k) a n − k b k that leads us to the following reasoning : Bases : For n = 0, ( a + b) 0 = 1 = ( 0 0) a 0 b 0. So, H 0 holds. Induction steps : For n + 1 : ( a + b) n + 1 = ( a + b) ( a + b) n As we assume H n holds, we have :
