While on a vacation in Australia, Mary took a taxi to travel kilometers from her hotel to the Sydney Opera House. The taxi charged her $2.19 Australian Dollars per kilometer. The conversion rate of US Dollars (USD) to Australian Dollars (AUD) during Mary's trip was 1 USD = 1.263 AUD. How much did Mary's taxi ride cost her in US Dollars (USD)?

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.
