(You really need to rewrite that sentence; however, I'll presume you are referrin to Buffon. Note that the act of dropping the pin may be independent of whether it lands on lines or polka dots.)

Maybe. Depends on the height of the pin release and the elasticity of both the pin and whatever the lines are drawn on.
