- A café serves breakfast every morning. Customers arrive for breakfast at random at a rate of 1 every 6 minutes.
Find the probability that
- fewer than 9 customers arrive for breakfast on a Monday morning between 10 am and 11 am.
The café serves breakfast every day between 8 am and 12 noon.
- Using a suitable approximation, estimate the probability that more than 50 customers arrive for breakfast next Tuesday.
