4.1 Total resistant(R) in an electrical circuit is calculated as follows: R = R₂ + R₂ + R, (series connection)
土 1+1+1
(parallel connection)
R;
If R= 40, R2 = 60 and R= 80 (n = ohm)
Calculate:
4.1.1 Ry(series)
4.1.2 Ry(parallel)​

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.
