Answer: 0.0123
Step-by-step explanation:
Given : Customers leaving a subway station can exit through any one of three gates.
The probability of selecting any particular gate = 
Sample size : n= 4
Using binomial distribution,
, where P(x) is the probability of getting success inn x trials , n is the number of trails and p is the probability of getting success in each trial.
Then , the probability that among a sample of 4 customers, they all exit through the same gate.

Hence, the probability that among a sample of 4 customers, they all exit through the same gate = 0.0123
