Unformatted text preview: ur work. 8. Let X be a uniform random variable in the interval [0,1], and let Y be an exponentially
distributed random variable with a mean value of 2. Assume that X and Y are independent. Find
and plot the probability density function of Z=X+Y. 8 9. A football stadium has 1000 light bulbs used to illuminate the field. The probability that each
light bulb is faulty when the switch is closed is 0.05. Use the centrallimit theorem to estimate
