What Are Probabilities ? #probability | Martin Butler

Math Central on Instagram: "A Galton pyramid (or Galton board) illustrates the Normal distribution by showing how many small random events combine to create a predictable bell-shaped pattern. As balls drop through rows of pegs, each bounce sends a ball left or right with equal probability. Although each individual path is random, most balls end up near the center because there are many more ways to take a balanced mix of left and right bounces than to take all left or all right. When many balls

Mathematisa | Math Animations on Instagram: "In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is f(x) = 1/√(2πσ²) e^(-(x-μ)²/(2σ²)) 📐 The parameter μ (mu) is the mean or expectation of the distribution (and also its median and mode), while the parameter σ² is the variance. The standard deviation of the distribution is
