I got 3 i know are correct but what about the others

On a probability quiz, you get two points just for showing up. The rest of the quiz has four questions such that the correctness of your answer for question i is given by the Bernoulli (p = 0.35) RV Xi.Your score for the quiz is Y = 2 + 2(X1 + X2 + X3 + X4).Assuming X1, X2, X3, and X4 are independent, please select the true statements. P[Y > 5] = 0.437 C] Cov[X2,Y] : 0.455 [3 E[(X2 + X3)(X1+ X4)] = 0.49 [3 Var[Y X2] = 2.958 C] E[YX2] = 2.74 0.179 y = 2 0.384 y = 4 2711:: 0.015 y 2 10 0 otherwise C] Fy(4) = 0.517 C] Var[Y] : 3.34 [3 c:ov[X1 + X3,X4] = 0 E[Y] = 4.8
