=+ 2. While taking a standardized test with randomly scram- bled answers, you notice that your last four answers have been "c." Which of the following is true concerning the probability of the next answer being "c"?

a. It is higher. Once a streak begins, it is likely to last for a while.

b. It is lower. Since answers are distributed randomly, "c" answers become less common.

c. It is unaffected by previous answers. It is as likely to be "c" as any other answer.

d. You should check your previous answers. Four "c's" in a row is impossible.

e. It is higher. Test constructors trick students by keeping the same answer many times in a row.
