You're right, he only wants the number of expected connected calls out of 1000... the odds per caller do not change, so once we have the odds, we just multiply by 1000 to get the expected number of live contacts.

And since the calls stop once he gets a single "five" (a live contact), the odds of subsequent rolls are irrelevant (because they won't waste time calling again).

So the odds of getting at least one "five" in 6 rolls is the 66.52 percent chance LambSlave gave...

Multiply that by 1000 target clients, and it gives you 665.2 likely live phone contacts if you stop at 6 tries, and you have a 16 percent chance of a live contact per attempted call.

Awesome!! That’s they information I trying to figure out. Thank you everyone!

Actually the odds of contact are reduced with every iteration of the list.

This is a replacement problem. If you are calling at the same time every day you cannot expect the customer to be home tomorrow night if they were not home tonight.

So, you need to calculate the entire process, rotating contact times, etc. Also you need to clear your list from the do not call lists in your state. The issues brought about from calling when you shouldn’t are not worth the effort for a temporary measure.
