Discrete random variables Xu and Fu both take values in 101

Discrete random variables X(u) and F(u) both take values in {-1,0,+1}. The joint probability mass function for X (u) and Y (u) is where K is a constant. Find and provide a label sketch of the conditional probability mass functions: Given that X(u) = i, find the best estimate of Y(u) under the Linear MMSE, MMSE, Maximum Likelihood, and Maximum A posteriori Probability criteria. Fill in the table below to describe your answer: What is the residual mean-squared error for the Linear MMSE estimator?
