Outcomes are thus triples of "girls" (g) and "boys" (b), which we write gbg, bbb, etc. For each outcome, let R be the random variable counting the number of boys in each outcome. For example, if the outcome is gog, then R(gbg) = 1. Suppose that the random variable X is defined in terms of R as follows: X=2R-2R"-3. The values of X are given in the table below. Outcome bbb bgg gog bgb gob ggg bbg ggb Value of X -15 -3 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. Value X of X Px (x) 0 X
