1. When building a tree house, it is important to make sure the sides are truly vertical, or plumb. The sides and floors must meet at right angles, so that the corners are square. The floors must be horizontal, or level. Make a statement explaining how each ofthe carpentry terms plumb, square, and level are connected to geometry, and a statement explaining how they relate to each other.

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.
