The drama club collected $160 from ticket sales for the spring play. they need to collect at least $400 to pay for new lighting for the stage. if tickets sell for $3 each, how many more tickets need to be sold. (side note, it is solving inequalities)

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

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.
