- TL;DR Summary
- Probability of picking ace from deck, 4/52, OK. But it's also "probability that the card is an ace and nothing else": i.e. (4/52)*(48/52). Why not?
The summary says it all: why is the probability of an event not calculated by the probability that it is the event AND that it is not any other? Sounds silly, and I am certain the explanation is simple, but I don't see it.
