Kindly answer task 4. I really need it. Thank you. Topic: Probabilities, Mean, and Variance of Discrete Variable

The probability distribution of a discrete random variable X is a listing of each possible value x taken by X along with the probability P(x) that X takes that value in one trial of the experiment. The mean u of a discrete random variable X is a number that indicates the average value of X over nwnerous trials of the experiment. It is computed using the formula u = EXP . (x) The variance o and standard deviation or of a discrete random variable X are numbers that indicate the variability of X over numerous trials of the experiment. They may be computed using the formula a' = [(x -4)2 . P(x) Task 4 Make your own experiment and trial. Choose your own random variable X and compute for its mean, variance and standard deviation
