Ineed . the passage suggests that a person is more likely to laugh at a movie: a. when he or she is one of a few people in the audience b. when there are many others laughing at the movie too c. after he or she has seen the movie several times d. if he or she is watching it at home on a videocassette recorder

Well this is a very strange question indeed since different personalities can result in different reactions to each situation, but since the passage says that laughter is contagious, I would believe that the answer be B.

Step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
