Question: An elementary student has 7 red blocks and 5 blue blocks. If they stack 3 blocks randomly, what is the probability that exactly 1 is red? - IQnection
Discover the Math Behind the Blocks: A Simple Dive into Probability
Why are young learners across the U.S. fascinated by fate, chance, and patterns? In an age where data shapes decisions—even in games, investments, and everyday choices—understanding probability helps decode uncertainty. One deceptively simple question captures this beautifully: What’s the chance that exactly one red block appears when stacking three blocks chosen at random from a set of seven red and five blue? This isn’t just a classroom math problem; it’s a gateway to how we interpret randomness in a digital world increasingly governed by algorithms, trends, and smart choices.

How to Calculate Exactly One Red Block in Three Drawn
To find the probability that exactly one of the three stacked blocks is red, we analyze combinations—one of the most effective tools in discrete probability. First, our pool contains 12 blocks total: 7 red and 5 blue. We want a stack of 3 blocks with precisely 1 red and 2 blue.
We count favorable outcomes by choosing 1 red from 7, and 2 blue from 5:
- Ways to pick 1 red: C(7,1) = 7
- Ways to pick 2 blue: C(5,2) = (5 × 4)/(2 × 1) = 10
- Total favorable outcomes: 7 × 10 = 70
