A box contains 12 red, 15 blue, and 18 green balls. If a ball is drawn at random, what is the probability it is not blue? This simple yet compelling question taps into a timeless curiosity about chance and chance-based probabilities—an ancient fascination that remains deeply relevant in today’s digital landscape. With growing interest in puzzles, games, and data literacy, this exact setup is increasingly shared across social platforms and educational content, especially where probability and statistics intersect with real-world decision-making. The scenario features 12 red balls, 15 blue balls, and 18 green balls—totaling 45 balls. To find the probability the drawn ball is *not blue*, we first calculate the chance of selecting blue, then subtract from 1. The probability of drawing a blue ball is 15 out of 45—easily simplified to 1/3. Subtracting that from 1 gives a 2/3 chance the ball is not blue. This clear calculation supports intuitive understanding, making it accessible to curious learners across the U.S. This concept isn’t just academic—it reflects how probabilities shape daily choices, from games of chance to statistical analysis in apps and platforms. In a world increasingly driven by data, understanding probability builds smarter decisions. Users are naturally drawn to such clear, factual examples, especially mobile-first audiences seeking reliable, no-fluff knowledge.
