favorite possible value of X yeah we're computers for every possible value of X because Y will be measured in this scenario Z will be measured so y and z will be numbers available to us x will not be known can take on many values and so we'll compute this for every value of x now after we've computed this for every value of x we'll have a table of all these four values of X and those entries if we ignore the bottom will not sum to one but we know it's supposed to be a distribution over x given y and z so then we know I also know we we
