How would I modify the max. and min. value of a bound?

I’m using the ‘bounds’ component to output a bound between 5 and 18. I’d like to plug that bound into a random number generator, but instead of 5 and 18, what would i do to modify it to, say 5 and 12, or 7 and 18? I’d like to modify either the lower or upper limit of the bound.

Thank you for any help!
