Mrs. Ross, a seventh grade teacher, has to choose a class representative. There are three girls and five boys who want to be the representative. She decides to roll a six-sided die to select the class representative. In this simulation, the odd numbers on the die represent girls and the even numbers represent boys. The simulation selected is , because the result of the experiment and the probability of the simulation .

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.
