In this figure, angles p and w are examples of

What figure are you talking about?

the answer could be supplementary: either of two angles whose sum is 180°.

complementary: either of two angles whose sum is 90°.

Vertical: each of the pairs of opposite angles made by two intersecting lines.

adjacent: two angles that have a common vertex and a common side.

step-by-step explanation:

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.
