The ace of spades from a deck
- Probability:
- 1.92%
- Odds:
- 1 to 51
- dBan
- −17.1 dBan
Only one card can reveal the ace of spades, so a single draw finds it once in 52 on average.
Calculation
p = 1 matching card / 52 cards = 1/52
Assumptions
A well-shuffled standard 52-card deck gives every card the same chance.
