Suppose a random variable has a probability density function (i.e. probability mass \ function) given by for :\ o 3 o 3 o " # $ &!-3 (a) What is the constant ?-(b) What is the probability that to two decimal places? \ #& (c) What is the expected value of to two decimal places? \ 3. (a) Use Maple to find the volume of the solid of revolution found by revolving the region bounded by sin , , and about the -axis. Give the 0B o B B o ! C o ! B o " B # answer to three decimal places. (b) Use Maple to compute a right hand sum with n = 200 subintervals which approximates the quantity computed in (a). Give the error of this approximation to three decimal places. I have adhered to the Duke Community Standard in completing this assignment. :___________________________________ Signature...
