State the domain and range of the following function. {(6,-8), (9,3), (-3,5), (1,-6), (5,7)}

A. Domain: {-3, 1, 5, 6, 9}; Range: {-8, -6, 3, 5, 7}
B. Domain: {-3, 1, 5, 6, 3}; Range: {-8, -6, 5, 7, 9}
C. Domain: {-3, 1, 5, 6, 3}; Range: {-8, -6, 6, 7, 9}
D. Domain: {-8, -6, 3, 5, 7}; Range: {-3, 1, 5, 6, 9}

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.
