Can anyone show me the solution to this problem?

Identify the type of experiment and its parameters for the following experiment:

According to historical records, there is an average of 1606 cases of heart attacks reported in New York City each year out of the 8,406,000 residents. A hospital would like to find the probability that at least six people experience a heart attack in a day. The answer is Poisson with = 4.4. How to come up with 4.4?

According to historical records, there is an average of 1606 cases of heart attacks reported in New York City each year out of 8,406,000 residents. What is the probability that at least six people experience a heart attack in a day? Write your answer out to 4 decimal places. the answer is 0.281. How?

After conducting each of the following experiments many times, which one should we expect to have a higher value for the sample mean?The correct answer is: binomial experiment with n = 10 and p=0.90. How?
