If only one of these statements is true, how many sisters have I got?

1.) "I've got ten or more sisters."
2.) "I've got less than ten sisters."
3.) "I've got at least one sister."


None. If statement 3 is true, then statement 1 can also be true, and vice versa. Statement 2 can be true by itself, but only if I have no sisters.
