(Remember to express your answer as a proportion.) 7. Many random number generators allow users to specify the range of the random
numbers to be produced. Suppose that you Specify that the range is to be all numbers
between 0 and 2. Call the random number generated Y. Then the density curve of the
random variable Y has constant height between 0 and 2, and height 0 elsewhere. What
is P (Y > 0.8)? (Remember to express your answer as a proportion.) ...
