What can be said about the cardinalities of the sample spaces of the events below? event a: flipping a coin event b: rolling a standard number cube a. the cardinality of event a’s sample space is 8 greater than event b’s. b. the cardinality of event b’s sample space is 8 greater than event a’s. c. the cardinality of event b’s sample space is 4 greater than event a’s. d. the cardinality of event a’s sample space is 7 greater than event b’s.

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.
