All of us are used to multiple choice tests. If all the exam questions have a choice of 4 different responses (a,b,c,d) what is the probability of randomly guessing the right answer?

See! You are all naturally mathematicians!

How does this relate to the formulas regarding probability? For example, if the probability of a correct answer was .25, what would the mean (aka expected value) of the distribution be if the sample size was 100?

Hint: mean=np
