   Question

   A generator of random numbers in a computer will spread its outcomes spread evenly over the entire interval from 0 to 1 when we make it generate a long series of numbers. We call this a so-called uniform distribution. A generator of random numbers produces a number X that lies in an interval 0.4 or in an interval 0,7. Which gray shaded area(s) does the probability P(X ≤ 0.4 or X > 0.7) assign?
