D. Unions

Solutions

Expert Solution

10. A. Always

Mutually exclusive events with positive probabilities means that events or outcomes of events cannot occur at same time therefore it means that they are always dependent on each other.

11. C. Multiply

To find Probability of intersection and events are also independent, then probability of one event is inside another events means intersection and due to this way of finding probability is insider and intersection we need to multiply probabilities of both independent events.

12. B. Mutually Exclusive

Any events which cannot occur simultaneously is always Mutually Exclusive and dependent.
