Morphology

a + pound + to + a + penny

The phrase uses a numeric/odds contrast (a pound versus a penny) which gives a clue that one outcome is far more likely, so there is some compositional logic. However, the conventional use of 'X to Y' as expressing betting odds/probability and the idiomaticized meaning 'very likely' is not fully predictable from the words alone and relies on cultural/figurative knowledge, so it is only partially transparent to learners.

Etymology

The saying a pound to a penny comes from betting: imagine someone bets a whole pound while the other person puts only a penny, so the first person must be very sure the result will happen. So, the phrase means 'almost certain' or 'very likely'.
