On a coordinate plane, a curved line labeled f of x with a minimum value of (1.9, negative 5.7) and a maximum value of (0, 2), crosses the x-axis at (negative 0.7, 0), (0.76, 0), and (2.5, 0), and crosses the y-axis at (0, 2). Which statement is true about the graphed function?

1. F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5).
2. F(x) > 0 over the intervals (-∞, -0.7) and (0.76, 2.5).
3. F(x) < 0 over the intervals (-0.7, 0.76) and (2.5, ∞).
4. F(x) > 0 over the intervals (-0.7, 0.76) and (0.76, ∞).

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.
