Vertical Angles

Step-by-step explanation:

A set of vertical angles is describe in Oxford dictionary as: each of the pairs of opposite angles made by two intersecting lines. As we can see here, angle 1 and 2 are on opposite sides of each other, while still residing on the same two intersecting lines.

a² + b²= c²

24² + 7² = c²

c= 25

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.
