Hi guys, this has been killing me but does anyone know how to incorporate weighted probabilities with random numbers? For example:

I need to have a random number between 1-9 and have these probabilities:
15%
210%
30%
420%
530%
610%
710%
810%
95%

<tbody>
</tbody>

Any help would be much appreciated!

I just need a formula please and thank you.

Need 1 part of a formula to always point to the same range? use $ signs: $V$2:$Z$99 will always point to V2:Z99, even after copying

Hi shg - how does this work?

Not being a mathematician, I can't see immediately the relationship between the percentages senx7810 wanted and the number you put in the curly brackets.

Thanks
