Solve by simulating the problem.

You have a 5-question multiple-choice test. Each question has four choices. You don’t know any of the answers. What is the experimental probability that you will guess exactly three out of five questions correctly? Type your answer below using complete sentences.

anonymous · Answer

your welcome. but that was only the "theoretical probability" there is no way to get any other unless you actually take a test and simulate it like that. But yeah, theoretically that is the answer. :)  hoped i helped.

Using combination notation:

$$
\large \bf 
\binom{5}{3}\dfrac{1}{4}^3\dfrac{3}{4}^2
=\dfrac{5	imes4}{2}\left(\dfrac{1}{4}ight)^3\left(\dfrac{3}{4}ight)^2=\dfrac{45}{512}
$$
