The discrete random variables x and y take integer values with joint probability distribution given by f (x, y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x, y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).

How are the solutions for |x +4|< -2 and |x +4| < 2 different? a they are not different, because the inequality is an absolute valueb the first inequality has no solution because absolute value cannot be negativec for one the solution is benveen two numbers. for the other, the solution is outside of the twonumbersd. for one the solution is a range of positive numbers, for the other, the solution is a range of negativenumbers
