Glad to hear that, I knew we had smart rainers.  A

That's what I said....all of them!

Hi, Conrad. I didn't know the answer. 

That's assuming there are no letters.

Good. I haven't lost my touch.

I would not have guessed that either. 

I would not have guessed that.  That is amazing

wow, now I know

It's nice to confirm AR is the place where questions can be answered.  

Well, Conrad, I guess I'm not one of the smart Rainers!

yes

 Good morning Conrad. When one thinks about it, it is simple math.

Good morning Conrad. Here I thought I was a math guy, I better stick to mortgages. I had no clue.

Conrad Allen I thought you were asking for one four digit combination!

And when it comes to lock-box with 4 digits, it's 10c4 - that's only 420!

Thanks Conrad. Now I know and it is easy to remember:) 

Yay!  Probability and stats paid off!

Yes, we do;  I agree.

That's amazing 

Your trivia is fun Conrad.

Very useful to know.

I love math questions! William Feela gives the precise real-world answer but Jeff Dowler CRS shows the easy way to figure it out.

4 codes numbers only give 9999 number. If you have to use 4 codes you option will decrease buy about 999, so that would leave it at about 9000

I have not failed. I've just found 10,000 ways that won't work! - Thomas Edison.

Conrad Allen This makes two I got.

10 to the 4th power - 10 options for 1st, 2nd and so on (10 x 10 x 10 x 10)

I did not do the math but am surprised at the number.

Yes, we know how to use Google for answers.

funny!

Thank you Conrad.

Who was the highest flying bird from a week ago?

I could have probably figure it out if I were so inclined or more likely I would have looked it up online.
