Hi Everyone,

If anyone knows how to calculate "The Odds" or "Probability" -- I really would appreciate your help.

Using one email address for sending - a total of 800 emails are sent to 45 differently located email addresses. Of these, 600 were to different individuals, but all located on the same Server. i.e. Fred@ThisServer.com - Bill@ThisServer.com - June@ThisServer.com and so on.

Of the 600 sent, a total of 100+ successful delivered receipts were obtained automatically when requested.

What are the odds on a failure rate (non-delivery) of FIVE out of the next 100 sends - particularly if it is the first 5 (to two different individuals only 3 + 2) that fail delivery, but not the next 95?

This is just a "one-off" ask - but it will help retain my sanity if someone can provide an answer.

Thank you,

Ian

Whats the difference between CONCAT and CONCATENATE?
The newer CONCAT function can reference a range of cells. =CONCATENATE(A1,A2,A3,A4,A5) becomes =CONCAT(A1:A5)
