please can you  explain how to solve the below foer each step 

 

 

Verify that the function corresponding to the figure to the right is a valid probability density function. Then find the following probabilities: 0.3 a. P(x<5) b. P(x > 4) c. P(3<x<7) 0.1- d. P(5<x<8) Verify that the function is a valid probability density function by confirming the given density function satisfies the probability density function properties. Select the correct choice below and, if necessary, fill in the answer box within your choice. O A. As f(x) > 0 for all values of x, the given function is a valid probability density function. the given function is a valid probability density As f(x) < 0 for at least one value of x and the total area under the density function above the x-axis is O B. function. (Type an integer or a decimal. Do not round.) O C. As the total area under the density function above the x-axis is , the given function is a valid probability density function. (Type an integer or a decimal. Do not round.) O D. As f(x) > 0 for all values of x and the total area under the density function above the x-axis is the given function is a valid probability density function. (Type an integer or a decimal.
