Answer:
13.53% probability that no customers arrive in a five-minute period
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
They arrive at a rate of two every five minutes
This means that 
What is the probability that no customers arrive in a five-minute period?
This is P(X = 0).
