A clock tower rings bell every hour. Every hour, it will ring once with probability 1/3 and twice with probability 2/3. The numbers of times the bell rings at different hours are independent.
If we stay on campus for 4 hours (we hear bell on 4 occasions) what is the probability that we hear in total 7 rings?
