Earthquake. The loss, in thousands of lives, due to an earthquake in a certain area is a variable with density curve y = (x 3)/4 for 0 < x < 2, and y = 0 otherwise. The area under this density curve to the left of any number x between 0 and 1 equals x 4/16.

a. Graph the density curve of this variable.

b. What percentage of losses exceed one thousand lives?
