You have a 5-question multiple-choice test, then n=5. The probability that you will guess exactly three out of five questions correctly is 

 $C_n^kp^nq^{n-k}=C_5^3p^3q^{5-3}= \dfrac{5!}{3!\cdot 2!} \left( \dfrac{1}{4} \right)^3\left( \dfrac{3}{4} \right)^2=\dfrac{1\cdot 2\cdot 3\cdot 4\cdot 5}{1\cdot 2\cdot 3\cdot 1\cdot 2} \cdot \dfrac{9}{1024} =$ 
$= \dfrac{90}{1024} = \dfrac{45}{512}$ .
