Answer the following questions. All logarithms are in base 2. If you choose to write a script to compute the answers, make sure to attach your code, but also write the answers. If you choose to hand-write your answer justify all your solutions. 1c) Which, if any, of the pairs (X₁, X2), (Xo, X2), and (Xo, X₁) are inde- pendent? Justify your answer. 1d) What is the conditional distribution of the random vector (X1, X2) given Xo = 2? Repeat for given Xo = 5. le) Are the random variables X₁ and X2 conditionally independent given Xo = 2? = 2? Repeat for given Xo = 5. 1f) What is the conditional distribution of X₁ given Xo = 5 and X₂ = 2? 1.
