sub question 4 and 5 please Two criminal cases/law suits are randomly assigned to one or more of three lawyers in a big law firm: Anna,Ben and Cameron (abbreviated to A,B and C). Let X₁ denote the number of contracts assigned to Anna andX₂ denote the number of contracts assigned to Ben. For some reason, completely beyond my control, we arenot interested in Cameron's escapades.1. Find the joint probability function of X₁ and X₂.2. Find the marginal distribution ƒx₁ (7₁) of X₁ and the marginal distribution fx₂ (₂) of X₂.3. Are X and Y independent? Give reasons.4. Calculate the expected values E(X), E(Y) and the variances V ar(X), Var(Y).5. Calculate the covariance Cov(X₁, X2) of X₁ and X₂ . Hint: Use definition-Cov(X,Y) = E[(X – E(X))(Y – E(Y))]ΣΣ(x − E(X))(y − E(y) * f (x, y))х у
