10. Two mutually exclusive events having positive probabilities
are ______________ dependent.
A. Always
B. Sometimes
C. Never
11. If two events are independent, we can _____ their probabilities
to determine the probability of Intersection.
A. Divide
B. Add
C. Multiply
D. Subtract
12. Events that have no sample space outcomes in common and
therefore, cannot occur simultaneously are:
A. Independent
B. Mutually Exclusive
C. Intersections
D. Unions
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.
