Astudent takes a 28-question multiple-choice exam but did not study and randomly guesses each answer. each question has three possible choices for the answer. find the probability that the student guesses more than 75% of the questions correctly. (round your answer to three decimal places.)

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ya

3 4 7 12 19

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know
