Five persons A, B, C, D, E are contesting an election in which 3 persons are to be elected. If C is elected unanimously, the probability that D gets elected is

Given C is selected So n(S)=4C2=6 If D is elected then we can select one other person So n(E)=3C1=3 P(E)=36=12 ∴ The probability that D  gets elected is 12
