After analysing months of sales data, the owner of an appliance store produced the following joint probability distribution of the number of computers (X) and printers (Y) sold daily. 1. Calculate the conditional probability distribution of X given Y=0, Y=1 and Y=2. 2. Compute the conditional expected values of X given Y=0, Y=1 and Y=2. 3. Verify the Law of Iterated Expectations, namely that E(X)=E[E(X|Y)].

Question

After analysing months of sales data, the owner of an appliance store produced the following joint probability distribution of the number of computers (X) and printers (Y) sold daily.

1. Calculate the conditional probability distribution of X given Y=0, Y=1 and Y=2.
2. Compute the conditional expected values of X given Y=0, Y=1 and Y=2.
3. Verify the Law of Iterated Expectations, namely that E(X)=E[E(X|Y)].
