    1)
    The equations for computing mean and variance are:
    Mean = Σx*P(x)
    Variance = Σ[(x-μ)2 * P(x)]
    x P(x) x*P(x) x - mean (x-mean)^2 (x-mean)^2 * P(x)
    2 0.50 1 -3.40 11.560 5.780
    8 0.30 2.4 2.60 6.760 2.028
    10 0.20 2 4.60 21.160 4.232
    mean 5.40 variance 12.040

    Mean = 2(03.50) + 8(0.30) + 10(0.20) = 5.40.
    Variance = 5.780 + 2.028 + 4.232 = 12.04.

    The mean is 5.40 and the variance is 12.04.
