In dividing two equation with variables and exponent, First you must align or rearrange the equation and group them base on their variables but don't forget the sign of each variables. Second, proceed in dividing its quantity and then subtract its exponent to the other variables having the same. So by calculating it, the answer would be X or X^1

A is the corect answer they congruent.
a) If f(y) is a probability density function, then both f(y) ≥ 0 for all y in its support, and the integral of f(y) over its entire support should be 1. eˣ > 0 for all real x, so the first condition is met. We have

so both conditions are met and f(y) is indeed a PDF.
b) The probability P(Y > 4) is given by the integral,

c) The mean is given by the integral,

Integrate by parts, with


Then
