A multiple choice exam offers four choices for each question. Jason just guesses the answers, so he has probability 1/4 of getting any one answer right. You want to simulate whether Jason's answers to 10 questions are right or wrong. One correct way to do this is
A) one digit from the random digit table simulates one answer, with 4 = right and all other digits = wrong. Ten digits from the table simulate 10 answers.
B) one digit from the random digit table simulates one answer, with 0 or 1 = right and all other digits = wrong. Ten digits from the table simulate 10 answers.
C) one digit from the random digit table simulates one answer, with odd = right and even = wrong. Ten digits from the table simulate 10 answers.
D) two digits from the random digit table simulate one answer, with 00 to 24 = right and 25 to 99 = wrong. Ten pairs of digits simulate 10 answers.
E) two digits from the random digit table simulate one answer, with 00 to 04 = right and 05 to 99 = wrong. Ten pairs of digits simulate 10 answers.
