Sonny Blackwell · Answer 1

Answer is (D) n

Step-by-step explanation:

Probability density function defines the likelihood of an outcome for a discrete random variable or a continuous random variable whose integral gives the probability that the value of the variable lies in the same interval.

The constant here is C

CX" implies CX prime prime (meaning that X has been differentiated twice).

The value of C is n, which is the number of values of X.
