What does compute is that some bacteria received the trait from their parents and others did not receive the trait for some reason and they died.
There are no "parents". Bacteria reproduce asexually, all the bacteria in the colony are clones of the original, plus whatever errors/mutations might have occurred in the DNA copying process. If the initial bacteria has no resistance to the anti-biotic and some of the following generations do, the only way they could have gained that resistance is by mutation.
