Question: Select the correct statements: I. P(E) + P(E‾) = 0. II. If an event is certain, than the probability of that event is 1. III. E ∪E‾ = S, where E is an event, E‾ its complement and S the sample space. IV. Number of events in the complement of selecting a king from a pack of cards is 50.
A ) II and III only B ) I and III only C ) I and IV only D ) II, III and IV only
Steps to derive
1 P(E) + P(E‾) = 1.
2 Probability of an event which is certain to occur is 1.
3 E ∪E‾ = S.
4 Number of events in the complement of selecting a king from a pack of cards is 48.
