Suppose that the genders of the three children of a certain family are soon to be revealed. 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 girls in each outcome. For example, if the outcome is bbg, then
R(bbg) = 1. Suppose that the random variable X is defined in terms of R as follows: X=R²-3R-4. The values of X are thus:
Outcome bgbgbbggbgggbbgbgggbg
Value of
-6 -6 -6 -4 -6 -6 -6
X

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