Risk has a mathematical formula. Risk = threat x vulnerability.
Now, you might have a perception that you can reduce risk by eliminating threats, but you really cannot do much about the threat. You can reduce it may be, but you can’t bring it to zero.
You can reduce vulnerability, it is much more in our control. Again, but not completely through.
But, while you are making decisions , it is good to know that you are playing around with those two variables.
