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 heads in each outcome. For example, if the outcome is thh, then N (thh)=2. Suppose that the random variable X is defined in terms of N as follows: X=2N²-6N-4. The values of X are given in the table below. Outcome ttt hhh hth hht tht htt thh tth Value of X-4 -4 -8-8-8-8-8-8 Calculate the probabilities P(X=x) of the probability distribution of X. First, fill in the first row with the values of X.
