Leonardo wants to find the height of the security camera on the wall in the lobby of his school. He puts a mirror on the floor and stands back until he can see the security camera in the mirror. He measures the distance from the mirror to the wall as 1.75 m. He measures the distance from the mirror to himself as 90cm. His friend measures his height as 166cm. How high is the security camera (in m, rounded to 2 decimal places)?

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.
