Random Variables and Univariate Probability Distributions Random Variables Random Variables Example 3 (3.3) Suppose we throw three fair coins.Then the space sample S-TTT,TTH,THT,HTT,HHT,HTH,THH,HHH. Let X()be the number of heads shown up.Then X(TTT)= 0,X(TTH)=1,X(THT)-1,X(HTT)-1,X(HHT) 2,X(HTH=2,X(THH)=2,X(HHH)=3.We have 2={0,1,2,3}.
