Qubit can be ZERO and ONE at the same time. Right?

1 and 0 can represent TWO (10) in a binary system. Right? Therefore one qubit can represent number 2. Right?

My question. When this qubit is used to give a result of a calculation (is measured/evaluated somehow at the end of a calculation) it collapses into only one defined state ONE or ZERO. Right? HOW IS IT MADE THAT THE ANSWER (from this qubit) IS THE NUMBER TWO (which it was supposed to be)?

Please excuse a layman for trying to get some idea of quantum computing and many thanks for attention.
