Your teacher is giving a test that has 5 more four-point questions than six- point questions. The test is worth 120 points. Which system represents this information? (A) x +5=y; 4x + 6y=120 (B) x+y=5; 6x + 4y = 120 x-y=5; 6x + 4y= 120 (D) x-y=5; 4.x + 6y= 120​

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.
