The length of a cell phone is 1.2
1.2 inches and the width is
4.8
4.8 inches. The company making the cell phone wants to make a new version whose length will be
1.02
1.02 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

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.
