First, identify the form of the series. It's a power series centered at x = 1. The terms are a_n = (-1)^n (x-1)^{2n+1}. It is not a standard power series ∑ c_n (x-1)^n because only odd powers a... |

Please reason step by step, and put your final answer within \boxed{}. | <think>
We are given that X and Y are independent and identically distributed according to Binomial(n, 1/2). We need to find P(X > Y).
Since X and Y are i.i.d. with the same distribution, by symmetry, P(X > Y) = P(Y > X). Also, we have P(X = Y) + P(X > Y) + P(Y > X) = 1. Since P(X > Y) = P(Y > X), we have P(X > Y) = (... |
