for the past 40 days katniss has been recording the number of customers at the hob between 10:00am and 11:00am during that hour
there have been fewer than 20 customers on 25 out of the 40 days.what is the experimental probability there will be fewer than 20 customers on the 41 day?20 or more customers on the 41 day?
Because in our sample of 40 days, the Hob has had fewer than 20 customers 25/40=5/8 of the time, the best estimate of the probability that there will be fewer than 20 customers the next day is 5/8. If the Hob had fewer than 20 customers 5/8 of the days, then it had at least 20 customers 3/8 of the days, so the best estimate of the probability that it has at least 20 customers the next day is 3/8.
