I was reading this article and at a certain point it is said
President Kennedy even estimated that the likelihood of nuclear war at one point was “between 1 in 3 and even”
that makes it the number 2, clearly, but what significance does it have?
"a likelihood of 2" does not mean much to me, also because the scale it is not specified (2 out of 2? out of 10? 100?)
Is it an idiom with a specific meaning and should I avoid taking it literally?
