Computation Question - Help Please

First let me say, thank you for your help in advance. I posted this on the web and haven't received an answer. I guess I need to ask some folks that know what they are doing. I am trying to learn how to calculate my chances of successfully winning at least one raffle when I enter multiple raffles at a time. Each raffle has it's own chances.

Hypothetical Question: (please show work)
How do I calculate the % chance of successfully winning at least one of the 3 raffles I have entered simultaneously?
Raffle 1: 0.2% chance of winning
Raffle 2: 3% chance of winning
Raffle 3: 14% chance of winning
