Solve the problem.Five horses (A, B, C, D, and E) are racing at the local track. According to the oddsmakers, A has a "one in four" probability of winning [i.e. Pr(A) = ], B has a "one in ten" probability of winning, and C has a "one in twenty" probability of winning. The remaining two horses both have the same probability of winning. Find the probability assignment for the probability space.

A. Pr(A) = , Pr(B) = , Pr(C) = , Pr(D) = , Pr(E) = 
B. Pr(A) = , Pr(B) = , Pr(C) = , Pr(D) = , Pr(E) = 
C. Pr(A) = , Pr(B) = , Pr(C) = , Pr(D) = , Pr(E) =
