Poisson Distribution Fitting - Online - excel data

We have daily rainfall data of 1979 and 1980. We want fit Poisson distribution on our data and find the probability of Poisson distribution when the rainfall is between 2 and 7 mm.
P=74.3%
Firstly you should calculate the parameters of Poisson Distribution based on your data then you can have your Poisson distribution function.
By using these parameters you can calculate the probability of Poisson distribution. So, you should follow these steps:
1. Prepare your data in excel or anywhere. For Poisson Distribution
2. Copy the data from excel (or any file) and use it on:

=============================================
Then you have the parameters of Poisson Distribution and you can use it on the calculator:
