Question
A boy is to sell lemonade to make some
money to afford some holiday shopping. The
capacity of the lemonade bucket is 1. At the
start of each day, the amount of lemonade in
the bucket is a random variable X, from which
a random variable Y is sold during the day.
The two random variables X and Y are jointly
uniform.
a) Write down the joint pdf of X and Y and
clearly indicate the region of interest.
b) What is the probability that the amount of
lemonade sold is less than 1/3?
c) Find and sketch the CDF and the pdf of "Z"
which is the amount of lemonade remaining
at the end of the day. Clearly indicate the
range of Z
