An ordinany (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 R be the
random variable counting the number of heads in each outcome. For example, if the outcome is thh, then R (thh) = 2. Suppose that the random variable X is
defined in terms of R as follows: X= 3R-R-4. The values of X are given in the table below.

Calculate the values of the probability distribution function of X, i.e. the function py. First, fill in the first row with the values of X. Then fill in the appropriate
probabilities in the second row.

Expert Solution
Step 1
We have given that
R= the random variable counting the number of heads in each outcome.
X=3R-R2-4
Sample space for R=((hhh,hht,hth,thh,tth,tht,htt,ttt))
