George Miller's theory of memory, known as the "magic number seven, plus or minus two," has influenced the design of information processing systems, such as websites and software interfaces, to ensure that they present information in a way that aligns with human memory capacity. This theory is also considered in educational settings to optimize learning strategies and help students retain information more effectively. Additionally, Miller's work has helped shape cognitive psychology research on memory and provided a framework for understanding the limits and organization of human memory.
It is 1: a certainty. A complete pack of cards must have a seven.
One seven of hearts exists in a deck of 52 cards.
There is only one of each individual card in a deck. While there are 13 cards of the heart suit, and 4 cards that have a value of seven out of the entire deck, only ONE card is a seven of hearts.
