Company SAFE insures its clients on office space availability. Should
a client has suffered a disaster i.e. fire, bomb alert, etc. SAFE
provides them with office space facilities where they can relocate
till their own offices become available. If client require space it
said client send an ?invocation?.

SAFE has 3000 seats available in London. Client A subscribed for 1000
seats, clients B, C, D and E subscribed for 250 seats each. Other 100
clients subscribed for 20 seats each. So total of 105 clients require
4000 seats if they all invoke simultaneously.

SAFE operated for 6 months and had 10 invocations during this time.
Each invocation was 10 days long on average.

How to calculate the probability that SAFE has seats in reserve to
support its customers? What is the probability of different customers
to invoke and how does it affect the probability of seats being
available?

How does adding new customers effect total seats availability? How
many customers they can support with given number of seats and what is
% probability?

This is for my course work at Uni.

Thanks

Should we assume that a invocation can be done for any number of seats
under contract for the client? or should the client make invocations
only for the total?

Invocation is made for total number of seats specified in the contract
