8. Below are the values of the probability mass function of a discrete random variable X. p(0) = P(X = 0) = 0, p(1) = P(X = 1) = 20, p(2) = P(X - 2) =1-30, where e is an unknown parameter. Suppose six randomly collected samples from X are ' 1 ', '2', 2', 1 ', 2', '0 '. Find the maximum likelihood estimate for & based on this sample
