A binomial distribution is the probability of something happening in an event. The binomial theorem widely used in statistics is simply a formula as below : \[(x+a)^n\] =\[ \sum_{k=0}^{n}(^n_k)x^ka^{n-k}\] …

This series converges for an integer, or (Graham et al. 1994, p. 162). When is a positive integer , the series terminates at and can be written in the form. (2) WebJan 19, 2024 · 5 Answers. Yes. You know that (1 + x)n = ∑nk = 0xk(n k). Just differentiate this expression. You will obtain n(1 + x)n − 1 = ∑nk = 0kxk − 1(n k). We can also use the binomial identity (n k) = n k (n − 1 k − 1). We obtain n ∑ k = 1k(n k) = n n ∑ k = 1(n − 1 k − 1) = nn − 1 ∑ k = 0(n − 1 k) = n2n − 1. how to talk to uscis live agent
