B) (i) is a correct statement but not (ii) or (iii).
C) (i) and, (iii) are correct statements but not (ii).
D) (ii) and, (iii) are correct statements but not (i).
E) All statements are false

Quizplus · Accepted Answer

Statement (i) is correct as it defines a probability distribution. Statement (ii) is incorrect because the probability of an outcome must be between 0 and 1, not 10. Statement (iii) is incorrect because the standard deviation is not the expected value; the expected value is the mean of the distribution.
