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 wewrite 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, thenR(bbg) = 1. Suppose that the random variable X is defined in terms of R as follows: X=R-- 2R-4.

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 bgb, then =Rbgb1. Suppose that the random variable X is defined in terms of R as follows: =X−2R−2R24. The values of X are given in the table below. Outcome bbg bgg ggg bgb bbb ggb gbg gbb Value of X −4 −8 −16 −4 −4 −8 −8 −4 Calculate the values of the probability distribution function of X , i.e. the function pX .
