Slanted Random numbers

i need to generate a series of “bubbles” with random radii, between say 5 and 15mm but i need “most” say 80% of the numbers generate to be closer to 5 than15 , ie fewer large bubbles and more smaller bubbles

i have completely random numbers currently using this

I feel like this is list manipulation or merge of two lists but my own attemtps so far have failed

Apologies no matter i just dragged them both into a number holder and it worked without the merge tool

you can also take advantage of graph mapper for that task
