If I'm right, all electronic component works on quantum probability. I was thinking all these electronic component works on classical physics only. Because probability will not produce 100% result, as and when desired.
I don't understand your question. EVERYTHING works on quantum probability. The difference between macro objects such as you and me is that the probabilities smooth out for macro objects so we can treat them with classical mechanics and get the right answer. If you want to get really nit-picky, there is no exact right answer out at the umpteenth decimal place because at that level of precision the probabilities matter and "exact" is invalid.
For the micro-level stuff that goes on in electronics, however, QM matters all the time.
