(ANYONE good at probabilities?)The train station runs trains every 30 minutes. Find the probability that a passenger who arrives at a random time will not have to wait more than 20 minutes.
A.1/3
B.1/2
C.2/3
D.25/30
The correct answer for this question is letter C. It is because the probability that a passenger who arrives at a random time will not have to wait for more than twenty minutes is 20/30. Then the lowest term of the probability is 2/3.
