The current in a semiconductor diode is often measured by the Shockley equation

$I=I_0(e^{aV}-1)$

where V is the voltage across the diode; $I_0$ is the reverse current; a is a constant; and I is the resulting diode current.

If $a=5,I0={10}^{-6},$ and V is uniformly distributed over $(1,3).$ Find the following:

$P\{V>2\}$ and $E[V]Var(V)E(I)Var(I)$
