a) \( \int_{-\infty}^{\infty} xf(x)dx\)
b) \( \sum_{i=1}^{\infty} x_i p(x_i)\)
c) \( \sum_{i=1}^{\infty} (x-\mu)^2 f(x)dx\)
d) \( \int_{-\infty}^{\infty} (x-\mu)^2 p(x_i)\)
b) \( \sum_{i=1}^{\infty} x_i p(x_i)\)
c) \( \sum_{i=1}^{\infty} (x-\mu)^2 f(x)dx\)
d) \( \int_{-\infty}^{\infty} (x-\mu)^2 p(x_i)\)
