Probabilities from the normal distribution

Since each deal Amir worked on (both won and lost) was different, each was worth a different amount of money. These values are stored in the amount column of amir_deals and follow a normal distribution with a mean of 5000 dollars and a standard deviation of 2000 dollars. As part of his performance metrics, you want to calculate the probability of Amir closing a deal worth various amounts.
