The following table gives the probability distribution of X, the number of defective products in a production line in a day.
x P(X=x)
0 0.04
1 0.19
2 0.35
3 0.26
4 0.16
a. Evaluate P(|X - expected value| >= standard dev)
b. The cost of maintaining the machine at the production line is given by C = 50 + 3x + 2x^2. Find the mean maintaining cost.
