Afisheye lens has a minimum focus range of 13.5 cm. of 1 cm is equal in lenght to about 0.39in. what is the minimum focua range of the lens in feet?

1cm = 0.39 in.

13.5 cm x 0.39 = 5.265 inches.

1 foot = 12 inches:

5.265 in / 12 = 0.43875 feet ( Round the answer as needed)

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.
