The number 7 has been traditionally associated with good luck and fortune in many cultures, and this belief has carried over into slot machines. In many slot machine games, the number 7 is often used as a symbol of luck and is featured prominently on the reels.
However, the probability of rolling a seven with a pair of dice is indeed related to its status as a lucky number in games of chance. When rolling two six-sided dice, the probability of rolling a seven is actually the highest among all possible outcomes, further contributing to its association with luck in games.
