Which of the Following Probabilities for the Sample Points A $\mathrm { P } ( \mathrm { A } ) = 0 , \mathrm { P } ( \mathrm { B } ) = 1 / 4 , \mathrm { P } ( \mathrm { C } ) = 3 / 4$

Which of the following probabilities for the sample points A, B, and C could be true if A, B, and C are the onlysample points in an experiment? .

A) $\mathrm { P } ( \mathrm { A } ) = 0 , \mathrm { P } ( \mathrm { B } ) = 1 / 4 , \mathrm { P } ( \mathrm { C } ) = 3 / 4$
B) $\mathrm { P } ( \mathrm { A } ) = 1 / 10 , \mathrm { P } ( \mathrm { B } ) = 1 / 5 , \mathrm { P } ( \mathrm { C } ) = 1 / 4$
C) $\mathrm { P } ( \mathrm { A } ) = - 1 / 4 , \mathrm { P } ( \mathrm { B } ) = 1 / 2 , \mathrm { P } ( \mathrm { C } ) = 3 / 4$
D) $\mathrm { P } ( \mathrm { A } ) = 1 / 8 , \mathrm { P } ( \mathrm { B } ) = 1 / 8 , \mathrm { P } ( \mathrm { C } ) = 1 / 8$
