1. 1.

   What is the mean of a Poisson distribution?

   Hint

   Refer to the parameters in the definition of the Poisson distribution.

2. 2.

   Can you provide an example of an event modeled by Poisson distribution?

   Hint

   Think of occurrences happening over a specific time frame.

3. 3.

   What is the mean of a Poisson distribution?

   • It's always 0
   • It's \\(\\lambda\\)
   • It's equal to the variance

   Hint

   Think about the parameters defined in the distribution.

4. 4.

   True or False: The Poisson distribution can model the number of events in a given time frame.

   • True
   • False

   Hint

   Recall the definition of the Poisson distribution.

5. 5.

   A hospital records an average of 15 patients visiting the emergency room per day. What is the probability that exactly 20 patients will visit tomorrow?

   Hint

   This is an application of the Poisson formula with specified parameters.

6. 6.

   In a certain cemetery, there is an average of 3 funerals held each week. Calculate the probability that in a week, there will be no funerals.

   Hint

   Assess how the average rate plays into calculating the probabilities.
