U is a continuous random variable on the range (0,1). A random variable X is defined by X=1/(1+6.5U).
Calculate the lower quartile of X and the expectation of X and add them together, reporting your result to 3d.p
Now I have no idea what to do for this one. I though of integrating between 0,1 of 1/(1+6.5U)
Please advice or give clue
Thanks
