Answer #1

Probability density function PDF:  

Cumulative dentisty function CDF: F(x)

i.e

The CDF is the integral of the PDF from negative infinity to the point of interest.

For the given question :

The probability density function and the cumulative distribution function are related as:

Answer :

d. None of the given answers.

-----

Note :

(option a. incorrect ; though looks to be correct  a. The PDF is the integral of the CDF from negative infinity to the point of interest.; But it shoudl be the otherway round :The CDF is the integral of the PDF from negative infinity to the point of interest.)
