1Answer both questions with explanation Consider two independent random variables X1 U(0, a), X2 U(0, b), where a is the last digit of your student number and b is the second last digit of your student number. For the random variables Y = X1 + X2: 1. What is the support of the distribution? Is the distribution continuous, discrete or mixed? 2. Draw the probability distribution function of the random variable? Justify your answer with either theoretically or logically. * a = 6 , b = 5
