Can someone help me Which function best models the graph shown below?
A f(x) = 0.25(0.5)*
B. f(x) = 0.5(0.25)*
c. f(x) = 0.25(-0.5)*
D. f(x) = -0.25(0.5)*

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.

the photograph is photographer and- in the process- ourselves.

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
