In taking a multiple-choice test, there are four possible answers for each problem, only one of which is correct. Assume that someone guesses randomly on all 25 problems.What is the probability of getting the first problem correct?

There are 4 equally likely answers, and only 1 is correct. So the probability of guessing the first problem correctly is 1 ÷ 4 = 0.25. The number of problems does not change the probability for this one question; the correct choice is 0.25.
