Explanation Given: The quartile points for a probability density function are the values x 1 , x 2 , x 3 that divide the area under the graph of the function into four equal parts. Definition used: Cumulative distribution functions : If f is a probability function and F ( x ) = ∫ − ∞ x f ( t ) d t is the associated cumulative distribution function. Calculation: The given function is f ( x ) = { 1 ( 1 + x ) 2 if x ≥ 0 0 othewise . If x < 0 , then F ( x ) = 0 . In case of x ≥ 0 , the value of F ( x ) is as follows. F ( x ) = ∫ − ∞ x f ( t ) d t = ∫ − ∞ 0 0 d t + ∫ 0 x 1 ( 1 + t ) 2 d t = ( − 1 ( 1 + t ) ) 0 x = − 1 ( 1 + x ) − − 1 ( 1 + 0 ) On further simplification, F ( x ) = − 1 ( 1 + x ) + 1 = − 1 + 1 + x ( 1 + x ) = x ( 1 + x ) Thus, the value of F ( x ) is F ( x ) = { 0 , x < 0 x 1 + x , x ≥ 0

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could co…
