Answer:
The probability that, in any hour, less than 2 customers will arrive is 0.0067.
Step-by-step explanation:
The random variable <em>X</em> can be defined as the number of customers arriving hourly at the drive-through window at the Fidelity Credit Union.
The random variable <em>X</em> describes a finite number of occurrences of an event in a fixed time interval.
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 7.1.
The probability mass function of <em>X</em> is:
Compute the probability of less than 2 customers arriving as follows:
Thus, the probability that, in any hour, less than 2 customers will arrive is 0.0067.
