spades

Represents the spades suit symbol commonly used in card game and probability notation.

Overview

A decorative symbol primarily used in mathematical texts, academic papers, and documents discussing card games, probability theory, or game theory.

  • Essential for typesetting card game strategies and examples
  • Frequently appears in probability problems involving standard playing cards
  • Used in combinatorial mathematics when discussing deck-related calculations
  • Pairs naturally with other card suit symbols for comprehensive card game documentation

Examples

Showing a spades suit in a probability problem involving playing cards.

P(drawing a spade)=∣♠∣52=1352P(\text{drawing a spade}) = \frac{|\spades|}{52} = \frac{13}{52} 
P(\text{drawing a spade}) = \frac{|\spades|}{52} = \frac{13}{52}

Representing a game theory payoff matrix involving card suits.

π(♠,♡)=5\pi(\spades, \heartsuit) = 5 
\pi(\spades, \heartsuit) = 5

Denoting a set of spade cards in a mathematical expression.

A={x∈♠:x>10}A = \{x \in \spades : x > 10\} 
A = \{x \in \spades : x > 10\}
