Las longitudes de los lados del rectángulo A son 6\text{ cm}6 cm6, start text, space, c, m, end text y 3.5\text{ cm}3.5 cm3, point, 5, start text, space, c, m, end text. Las longitudes de los lados del rectángulo B son proporcionales a las del rectángulo A.

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.

answer: check all that apply, where the options?

step-by-step explanation:

its kinda hard to answer this when we dont have all the information that we need.
