Ok, imagine this scenario. A good friend is going to die unless you do something about it. Let's assume that if you decide to take action (minimal effort needed), you will save your friend 100% of the time. The catch is, there is a risk on your own life. (You can only die or come out untouched. No in-betweens.)

Clearly, everyone would rescue their friend if the chances of dying themselves was 0%. However, most people would not save their friend if the chances of dying themselves was 100%.

So OOT, what odds do you need to go ahead and rescue your good friend?
