For exercises 19-24, suppose m is the line with
equation x = -5, line n is the line with equation
y= 1, line g is the line with equation y = x, and
line h is the line with equation y = -2. given
a(9, -3), b(6,4), and c(-1,-5), what are the
coordinates of the vertices of aa'b'c for each
reflection?
19. rx-axis
22. rn
20. ry-axis
21. rm
23. rg
24. rh

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 is 144
