Question About the Multiplying Damage Attack Effects

[Shinobi Mistress]

Okay, let me put it like this. For example, R/S 60/109 Mudkip's Fury Swipes does 10x damage. Let's say you flip your 3 coins and get all tails. Will this attack do 10 damage, or will it do 0?
Thanks in advance for answering my question!

It will do 0 damage.
