An ordinary (fair) coin is tossed 3 times Outcomes are thus triples of "heads" (h) and tails" () which we write th, trt, etc. For each outcome, let be the random variable counting the number of heads in each outcome. For example, if the outcome is then N () -0. Suppose that the random variable X is defined in terms of N as follows: X-N2-22-4, The values of Xare given in the table below. Outcome that helhether the ith the Value of x-5 - -1 -5 -4 -5 -4 -4 Calculate the probabilities PC) of the probability distribution of X First in the first row with the values of X Then in the appropriate probabilities in the second row. 8 6 BU Vahoo xoxo 0 D X 2 P(X) 0 0
