A good probability model

NHTSA has estimated that the average  18-30 y.o driver with a car accident has a 6.5% probability of having at least one police-reported car accident last year.  If we study medical interns on a typical hospital overnight schedule,  then among 20 interns, 5 report having a car accident  last year. The interns have the same risk of having a car accident as a typical 18-30 person. What is a good probability model for the number of interns with at least one car accident last year?

Thank you for the opportunity to help you with your question!

A good probability model for the number of interns with at least one car accident last year is the binomial pdf, with n=20 and p= .065 (same as a typical 18-30 person)
