Please help me

Problem 2. Let X1, X2, .... Xn be a collection of independent random variables that all have the same distribution (which implies they all have the same expectation E(X;) = / and variance Var(X;) = o'). Use properties of expectation and variance to show that the expected value of the random variable Y defined below satisfies E(Y) = 02: Y = i=1
