There are the correct number of nines in my first two posts, but muffed it with the pdf.

When will you be posting the follow-up problem?

Well, usually, when you post a problem as easy as this one was, there is another similar problem right after it...

That is good reasoning but in this case I can not post the follow up.

Hi Bobby,

I thought you had too few in the title.

Yes, you're right about that.

But something weird's going on and it's got me stumped.

I remember now that after I created the pdf from Word where I'd typed in "299999999999999" (in 1-point font), the pdf doc showed one less nine (ie, 13), and without thinking I added one more nine to the Word doc and created another pdf...which then showed 14 nines. So I uploaded that into the sky and posted the link.

Now when I download the pdf file from the sky and open it in PDF-XChange Viewer, Nitro or Adobe, 14 nines show up, but when I copy/paste from those programs into my image viewer (IrfanView), 14 nines show for Adobe but 15 for the other two.

Also, copy/paste from Google Chrome's browser's pdf viewer into IrfanView gives 15 nines, but I can't check the browser's pdf because I can't magnify it enough.

Hi;

That is weird. Sounds like you are experiencing incompatibilitis. It is a common ailment.

Maybe it's to do with the font I used. I won't try to sort that out.

The picture below is what I am getting:

Okay and have a good night. See you later.

Hi Bobby,

I used Inkpen2 Script as the font, which displays in my pdf viewers as per the image below. However, in Word, which is the source for the pdf creation, the 2 is in line with the nines and is spaced like the other figures.

I guess that shrinking the font upset things when saving to pdf.

Could be that Word added a control character in that string. It happens in M too.

**New problem:**

A bank robbery occurs every 29 days. If the police choose a day at random and then stake out the bank for 10 successive days what is the probability they will witness the robbery?

**A says) 9 / 29**

**B says) 10 / 29**

**C says) A is right for the 200th time in a row!**

**D says) In a row? A row of what?**

**E says) I have no idea.**

I have the result, but I do not yet know how to get it.

Is it like: one day robbery happens, then 28 days gap, then a robbery, and so on ?

Yes, I would say so. Let's assume the police have not picked up on the 29 day pattern and choose 10 days in a row starting from an initial random day.

I have the result, but I do not yet know how to get it.
