Probability: The Card Deck Shuffle
Explore probability concepts through interactive card deck simulations. See how probabilities change when drawing cards with replacement (independent events) versus without replacement (conditional probability).

Probability measures the likelihood of an event occurring. When drawing cards from a deck, probabilities change based on whether cards are replaced (independent events) or not replaced (dependent events). Conditional probability calculates the probability of an event given that another event has occurred.
The Mathematics of Probability
Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1. A probability of 0 means the event is impossible, while a probability of 1 means the event is certain.
Example for drawing a heart from a full deck:
- Favorable outcomes: 13 hearts
- Total outcomes: 52 cards
- P(Heart) = 13/52 = 1/4 = 0.25
- Independent Events: The outcome of one event does not affect the probability of another (drawing with replacement)
- Dependent Events: The outcome of one event affects the probability of another (drawing without replacement)
- Conditional Probability: The probability of an event given that another event has occurred, denoted as P(A|B)
