Математическое ожидание (E(X)): (1*0.15) + (2*0.22) + (3*0.14) + (4*0.08) + (5*0.32) + (6*0.09) = 0.15 + 0.44 + 0.42 + 0.32 + 1.60 + 0.54 = 3.47.
Дисперсия (D(X)): E(X²) - (E(X))² = [(1²*0.15) + (2²*0.22) + (3²*0.14) + (4²*0.08) + (5²*0.32) + (6²*0.09)] - (3.47)² = [0.15 + 0.88 + 1.26 + 1.28 + 8.00 + 3.24] - 12.0409 = 14.81 - 12.0409 = 2.7691.
