See how many random left-or-right bounces build a predictable distribution.

🎮 Try It
Change the probability of going right and the number of rows. Drop one ball, ten, the maximum, or a continuous stream. Compare counts with fractions, and in Lab mode compare your bars with the theoretical curve.

🎯 Your Mission
Before dropping 100 or more balls, predict where the tallest bin will be for a right-bounce probability of 0.70. Test your prediction and explain the pattern.

🌍 Real-World Connection
Similar probability patterns appear when repeated random variation affects measurements or manufactured parts.
