The following table gives the probability distribution of X, the number of defective products in a production line in a day.(adsbygoogle = window.adsbygoogle || []).push({});

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.
