Welcome back ibrahimrashidatu247 — missed you this week. Step 1: Identify the formula for variance and the given values. The variance of a random variable X is given by the formula: Var(X) = E(X^2) - (E(X))^2 From the image, we can infer the following: The values of x are: -3, -2, -1, 0, 1, 2, 3. The corresponding probabilities P(X=x) are: P(X=-3) = 0.05 P(X=-2) = 0.1 $P(X=-1)
