An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (h) and "tails" (t) which we write hth, ttt, etc.For each outcome, let N be the random variable counting the number of tails in each outcome. For example, if the outcome is hth, then N (hth) = 1. Suppose that the random variable X is defined in terms of N as follows: X= 2N-2N^2-2. The values of X are given in the table below.Outcome ttt hht thh tht tth hhh htt hthValue of X -14 - 2 - 2 -6 -6 -2 -6 -2Calculate the probabilities P(X=x) of the probability distribution of X. First, fill in the first row with the values of X. Then fill in the appropriate probabilities in the second row..Value x of X ______ _______ ______P(X=x) ______ _______ ______
