Group (A) Q1: A fair 4-sided die, with the numbers 1, 2, 3, 4 is rolled twice. If the score on the second roll is strictly greater than the score on the first the player wins the difference in euro. If the score on the second roll is less than the score on the first roll, the player loses the difference in euro. If the scores are equal, the player neither wins nor loses. What is the probability density function of X illustrating with graph? Let X denotes the winnings of the player (X can take any of the values −3, −2, −1, 0, 1, 2, 3 ). Q2:Determine the receiver probability values p(y1) and p(y2) for the channel below, p(x1)=0.4 Bounce question:(2 marks) Suppose the range of a discrete random variable is {0, 1, 2, 3, 4}. Ifthe probability density function is p(x) = cx for x = 0, 1, 2, 3, 4, what is the value of c?
