For example, in the example for calculating the probability of rolling a “6” on two dice: P (A and B) = 1/6 x 1/6 = 1/36. Take 1/36 to get the decimal and multiple by 100 to get the percentage: 1/36 = 0.0278 x 100 = 2.78%. WebExample 13.3.4 A sampling demonstration of the CLT. Consider a population random variable X ~ uniform [-1, 1]. Then E[X] = 0 and Var[X] = 1 / 3. We take 100 samples of size 100, and determine the sample sums. This gives a sample of size 100 of the sample sum random variable S100, which has mean zero and variance 100/3.
