The probability of a girl getting a line busy every time when she calls is 1/3 and if she makes one call on each of 4 consecutive days, then

A: Probability of getting the line busy on each of the 4 days

B: 1/4

C: A and B are equal

D: It's not possible to answer

[My Solution]

Since each days is a separate Possible Outcome which is 1/3 and she calls one time each day, then on each of the days the probability that she gets the line busy is 1/3

Is that true? Thank you
