1. Calculate the mean and standard deviation of the sum or difference of random variables.

2. Find probabilities involving the sum or difference of independent Normal random variables.

Matt...our GOALS 🙄​

After much thought, Mr. Turner has finally decided on permanent employee wages – no more daily wage nonsense. The permanent employee wages are randomly assigned using the probability distribution X, which is given in a table. Additionally, at the end of every year, Mr. Turner will give his employees an hourly wage. The bonuses are assigned randomly according to the probability distribution Y, which is given in a table. Assume X and Y are independent.

Equations we need:

Probability Distribution X

Probability Distribution Y

We can find the probability distribution of N.
