any other hmt member know anything about college statistics?
 

so i have a take home test in my statistics class and i cant figure out how to set up this problem... i mean it seems easy but i have tried everything to get the answer and i cant! every answer i come up with isn't one of the four answers my professor gave me see if you can figure it out

if a student randomly guesses at 20 multiple choice questions, find the probability that the student gets exactly four correct. each question has four possible choices


a .19
b .17
d .08
c .23
