If you are fratenal and your parents didn't use fertility treatments then your chances are definitely higher than most people's. I don't know the statistical probabilty, but you can probably do a little research and find it.
If you are all 3 identical or if your parent's used fertility treatments to conceive, then your odds should be the same as anyone else. Identicals are not caused by genetics.
