Two distinct cubes are thrown. The random variable X identifies the difference, that is the amount of the difference in the number of the eyes. Calculate the expectation value and variance.
$E\left ( X \right )=$
$V\left ( X \right )=$
Note: Enter the result to a minimum of 6 commas, or exactly.
$E\left ( X \right )=$Solution is $(35/18)$
$V\left ( X \right )=$Solution is $(63005/23328)$
Can someone give me some directions?
