Fill in the blanks: are typically treated with and orchiectomy and chemotherapy, while are typically treated with an orchiectomy and radiation therapy.

In your miRNA analysis the goal was to identify:

From the joint distribution of X and Y, find the joint distribution of X and |X-Y|. Fill in the blanks in the table with numbers. [number]

Given the exposure level was 0.5 for a group of patients, compute the expected level of the severity of symptoms. Compute three digits after the decimal point.

The clinician asked again to find the distribution of the severity of the symptoms given that the patient had a certain level of exposure. This conditional pdf can be written as follows. Fill in the blanks with the numerical answers.  conditional pdf: ([c0] + [c1]x + [c2]y)/([d0] + [d1]x + [d2]y)    

[Q1-Q3] Suppose random variables X and Y represent the level of exposure to some toxic chemical (0 to 1) and the level of severity of symptoms (0 to 5). Their joint pdf is given as    and 0, otherwise. Show your work on the scratch paper answering Q1-Q3 below to receive credit.
