# The sum of the probabilities

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

a- P(A)= 1/8, P (B) = 1/7, P(C)= 1/10

b. P(A)= 1/4 P(B)=1/4, P(C)=1/4

c. P(A)= -1/4, P(B)= 1/2 P(C)=3/4

d. P(A)=0, P(B)= 1/14, P(C)=13/14.

#### Solution Preview

P(A) + P(B) + P(C)

= 0 + 1/14 + 13/14

= 14/14

= 1
