Help!! -Lesson: Probability. (Please explain why as well! )

It is likely that the moon will be visible on the planet tonight. (Likely).

Step-by-step explanation:

 Let me explain why the other choices are wrong. We know that the moon is a satellite that orbits around Earth. Within that period of the moon revolving or orbiting, it is very likely that the moon will appear. It is not impossible because the moon does have light caused by a light wave being reflected from the sun, and that light on the moon can be visible from Earth, so it is not impossible. As likely as not is wrong because the moon is visible very likely within its period of orbiting. Unlikely is wrong because although the moon may not show during a new moon, that doesn't mean that moon will most likely never show up. Likely is correct because we can the moon from Earth almost on a daily basis throughout the month. Hope this helps!
