You 3D print a large batch of plastic parts, but X~ Poisson (5) parts have been printed with errors. You have a budget of $100, but you have to pay $10 to correct each error. Let R be your remaining budget after the repairs (R may be negative). Express R as 1234 a function of X. Give the expected value of X, and use it to find the expected value of R.

4 3D printing ~ You 3D print a large batch of plastic parts, but X Poisson (5) parts have been printed with errors. You have a budget of $100, but you have to pay $10 to correct each error. Let R be your remaining budget after the repairs (R. may be negative). Express R. as a function of X. Give the expected value of X, and use it to find the expected value of R. A Poisson (A) random variable has variance A. Use this to find the variance of R.
