WebFeb 5, 2024 · This is a good way to interpret the mean of a discrete random variable. Mathematically, the mean μ is the sum of all the possible values, weighted by their probabilities. As a formula, this is: μ = E[X] = ∑ all x[x ⋅ P (X = x)] In our case, this works out to be: μ = [0 ⋅ P (0)] + [1 ⋅ P (1)] + [2 ⋅ P (2)] + [3 ⋅ P (3)] WebRandom variables can be any outcomes from some chance process, like how many heads will occur in a series of 20 flips of a coin.
