A multiple choice examination has 5 questions.
\( \mathrm{P} \) Each equation has three alternative answers of
W which exactly one is correct. The probability that a student will get 4 or more correct answers just by guessing is:
(1) \( \frac{17}{3^{5}} \)
(2) \( \frac{13}{3^{5}} \)
(3) \( \frac{11}{3^{5}} \)
(4) \( \frac{10}{3^{5}} \)
