The events E and F are independent. If P ( E )=0 · 3 and P ( E ∪ F )=0 · 5, then P ( E / F )- P ( F / E ) equals:
The events E and F are independent. If $\displaystyle \mathrm{P}(\mathrm{E})=0 \cdot 3$ and $\displaystyle \mathrm{P}(\mathrm{E} \cup \mathrm{F})=0 \cdot 5$, then $\displaystyle \mathrm{P}(\mathrm{E} / \mathrm{F})-\mathrm{P}(\mathrm{F} / \mathrm{E})$ equals :
