1.  Explain why the EM algorithm would not work if there were just two
    attributes in the model rather than three.

2.  Show the calculations for the first iteration of EM starting from
    Equation (<a class="equationRef" title="" href="#">candy-64-equation</a>).

3.  What happens if we start with all the parameters set to the same
    value $p$? (<i>Hint</i>: you may find it helpful to
    investigate this empirically before deriving the general result.)

4.  Write out a
