This is Statistics question: (don t insert picture plz)

Mario, one of the owners of Mi Casa Front Porch Restaurant was looking to improve his planning for capacity. In order to do this, he wanted to understand the probability of people in each party coming to the restaurant. If the mean number of people per party is 3, what is the probability that the party will be 2 or 4 using the Poisson distribution? How would this influence Mario and his planning for capacity at the restaurant?

Based upon the scenario above, calculate and interpret the probability using the Poisson distribution in a minimum of 150 word essay.
