35 Users

1 Mb/s link

each user: 100 kb/s when "active"

a) 10 active at the same time is less than .0004%, how did we get that value?

b) With 35 users, whats the probability of more than 10 users active at one time?

c) What happens if more than 35 users are active at once?

Please show probability calculation.
