<ul><li>The post explains the connect between normal probability approximation and the cumulative distribution function (CDF) of a normally distributed random variable.</li><li>The CDF of a normally distributed random variable with mean μ and variance σ² is shown.</li><li>Python code is provided to demonstrate the accuracy of the approximation.</li><li>The resulting plot shows that the approximation closely matches the exact value within the resolution of the plot.</li></ul>
