Webb3 sep. 2024 · To find the variance of a probability distribution, we can use the following formula: σ2 = Σ (xi-μ)2 * P (xi) where: xi: The ith value μ: The mean of the distribution P (xi): The probability of the ith value For example, consider our probability distribution for the soccer team: The mean number of goals for the soccer team would be calculated as: WebbA random variable X is said to be a Bernoulli random variable with parameter p, shown as X ∼ Bernoulli(p), if its PMF is given by PX(x) = {p for x = 1 1 − p for x = 0 0 otherwise where 0 < p < 1 . Figure 3.2 shows the PMF of a Bernoulli(p) random variable. Fig.3.2 - PMF of a Bernoulli(p) random variable.
