There's no way to give you an exact number, but let me put it this way:
If you've disable as much as you can (which by default, most stuff is
disabled, so that's good), and you restart Apache after each update,
your chances of being broken into are better by things like SSH brute
force attacks. There's always a chance someone will get in, but when you
look at the security hole history of Apache, particularly over the past
few years, there have been numerous CVE's, but workarounds and they aren't
usually earth-shattering. Very few of them have. The latest version that
ships with 5.7 is as secure as they come. If it wasn't, most web sites
on the Internet would be hacked by now, as most run Apache.
