If a multiple choice test has five answers what is the probability of guessing the right answer?
You have a 50% chance of getting the right answer and a 50% of getting the wrong answer. You best bet is to eliminate your three worse/wrong answers and that leaves you with two that are more or less correct . I have taken tests where points are taken away for guessing. Each right answer was one point and for every wrong two points were taken off. This was a national standardized test. In all the testing I have taken I have no way to beat the system set up by testing. I have taken the LSAT, GRE, SAT, ACT, National Teachers Exam, and several others. Nothing beats getting the test prep book and learning the tricks for that particular test.

What is audio sampling?
This depends on the usage of the word. Usually, it refers to either one of two things. 1) taking a short segment of a sound or song such as a single drum beat or a short piano riff and saving it as a new audio file. This is usually used in "mashups" and sound collages or as triggers in live performances. 2) the frequency at which data is taken to describe a sound wave. You can think of this as plotting X and Y coordinates on a graph to describe a sound wave which a computer can translate into speaker movement and finally sound. The higher the sample rate, the higher quality the audio.
