Which of the following incorrectly describes the discrete probability distributions and continuous probability density functions?

A) They both reflect the distribution of a random variable.
B) They both have outcomes, which occur only in integers.
C) They both assist in determining the probability of a given outcome.
D) They are both relative frequency distributions.
E) None of these.

Discrete probability distributions are characterized by outcomes that can only take on integer values, such as the number of heads in a series of coin tosses. Continuous probability density functions, on the other hand, deal with outcomes that can take on any value within a given range, such as the exact height of individuals in a population. Therefore, statement B is incorrect because it inaccurately describes continuous probability density functions.
