Maya stands so that her shadow ends at the same place as the shadow for a lighthouse. The angle of elevation to the Sun from the tip of the shadows passes
through the top of her head and the top of the lighthouse. She carefully made the
scale drawing of the situation shown.
a. What is the distance from Maya to the lighthouse indicated by x on the scale
drawing?
b. If Maya's actual height is 6 feet, what is the actual distance in feet from Maya
to the lighthouse?

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.

1 + (6 / x - 1)
