To elaborate: It's .1% per non boss pokemon, there's 2 of those a wave so 90 in a level. 0.001*90=0.09 or 9%.

Also worth noting is that a 9% chance per level means that you will, in the long run, find a lapras every 11.11 (2dp, but the .11 is recurring) times you do the level. The working being 1/.09=11.11111 (recurring).
