The New York Yankees scored 859 runs and play in the American League, where the mean number of runs scored was 721.2 and the standard deviation was 93.5 runs. The Cincinnati Reds scored 790 runs and play in the National League, where the mean number of runs scored was 700.7 and the standard deviation was 58.4. Which team had a relatively better run producing season

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.
