![**Problem Statement:**
Records show that the average number of births at Highland Hospital per hour is 8.1. Find the probability of between 5 and 7 births at Highland Hospital (endpoints included) in a given hour.
Round your answer to three decimal places, and include all written work using the probability mass function. Do not use graphing calculator distribution commands or R.

**Explanation:**
To solve this problem, you need to use the Poisson probability mass function (PMF), which is suitable for modeling the number of events in a fixed interval of time given a known average rate of occurrence.
The PMF of a Poisson distribution is given by:
\[ P(X = k) = \frac{e^{-\lambda} \cdot \lambda^k}{k!} \]
where:
- \( \lambda \) is the average number of events (births) in a given time period (8.1 in this case),
- \( k \) is the actual number of events you want to find the probability for (5, 6, or 7 births),
- \( e \) is the base of the natural logarithm (approximately equal to 2.71828).
To find the probability of between 5 and 7 births, you need to calculate:
\[ P(5 \le X \le 7) = P(X = 5) + P(X = 6) + P(X = 7) \]
Calculate each term using the PMF formula and add the probabilities to get the final result, rounding the answer to three decimal places.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8f5de5c0-4789-4438-ad2e-39c0209f7c7c%2F5b0f447d-ed3f-4ded-87be-a79d30a951af%2Fktisxlc_processed.png&w=3840&q=75)
