#### Answer

Fill the blanks with
... $P(E)$ ... $number\ of\ outcomes\ in\ E$ ....
... $total\ number\ of\ possib1e\ outcomes$ ...

#### Work Step by Step

The theoretical probability of event $E$ with sample space $S$ is:
$P(E)=\displaystyle \frac{number\ of\ outcomes\ in\ E}{total\ number\ of\ possib1e\ outcomes}=\frac{n(E)}{n(S)}$.
