Solution

The correct option is C Probability density function
We know that, the probability density function is used to specify the probability distribution of the random variable falling within a particular range of values.
We know that the random variable falling within a particular range of values is continuous random variable.
Thus, a formula or equation used to represent the probability' distribution of a continuous random variable is called probability density function.
Hence, option C is correct.
