The “limited plan” offers a 15% discount for power usage between 7pm – 9am if most of your usage happens during that time. if not, then you lose your discount and you pay a 20% premium on the usage outside of that time. the cost per kilowatt hour is $0.05432. how much would you have paid in march if you used 450 kwh 7pm – 9am and 465 kwh 9am – 7pm?

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.
