I heard of the expression 'a hundred to one'. and I am perplexed. because I heard of that the expression has both positive and negative meaning at the same time.
I can't understand it. And moreover, as for its positive meaning I don't accept that one of hundred(1/100) has the meaning of 'certain, probable'. In my mother tongue, eight or nine of ten(80/100 or 90/100) means 'nearly certain'.
It has not worked out in my brain without somebody's help. so please help me.
