At a particular restaurant, each mozzarella stick has 90 calories and each onion ring has 50 calories. A combination meal with mozzarella sticks and onion rings is shown to have 960 total calories and 3 times as many mozzarella sticks as there are onion rings. Determine the number of mozzarella sticks in the combination meal and the number of onion rings in the combination meal.

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.
