Q. 15 Give classical (Laplacian, mathematical)
definition of probability.
The American Mineralogist (Oct. 2009) published a study of the evolution of uranium minerals in the Earth's crust. Researchers estimate that the trace amount of
uranium x in reservoirs follows a uniform distribution ranging between 1 and 3 parts per million. Complete parts a through c.
a. Find E(x) and interpret its value. Select the correct answer below and fill in the answer box to complete your choice.
(Simplify your answer.)
O A. E(X)=
This value gives the minimum parts per million of uranium for the collection of all reservoirs on the Earth.
O B. E(X)=
This value gives the maximum parts per million of uranium for the collection of all reservoirs on the Earth.
O C. E(x)=
This value gives the mean parts per million of uranium for the collection of all reservoirs on the Earth.
O D. E(X)=
This value gives the mean parts per million of uranium in each reservoir on the Earth.
