This is the use of probability when one or more cards are chosen from a deck or a card set.
Practice This ConceptMain explanation
Teacher explanation
Card questions test careful counting of suits, colours, and ranks. In a standard deck of 52 cards, there are 4 suits and 13 cards in each suit. Students should remember that probabilities depend on the exact property asked, such as a heart, a face card, or an ace.
Example
The probability of drawing a heart from a standard deck is 13/52 = 1/4.
Simple analogy
Suit, colour, or rank: count the right group first.
Common confusion
Students often confuse a suit with a rank and count too many or too few cards.
Exam tip
For card problems, first decide whether the question asks about suit, colour, rank, or face card.
