Sy is concerned about the staff needs at a supermarket that he manages. Because of the Enhanced Community Quarantine, there have been a decrease in the number of customers. Mr. Sy believes that the customer averages 9 visits to the store over a 30-day period. What is the probability that a customer visits the store 4 times in a 10-day period? The average number of relief goods your household receives during a pandemic is 3 per month. What is the probability that exactly 4 relief goods will be received by your household next month?
