Filled in circle means equal to or greater/lesser than. Arrow points the same way as the inequality symbol.

D. q ≥ -15

Step-by-step explanation:

since it's closed circle it's or equal to, if it's opened then it's not or and equal to, in this case it's closed.

It goes from -15 up so, it's bigger than or equal to -15.

q ≥ -15

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.
