Calculate the probability of obtaining sales

[#1]

I am pleased to greet you, some questions ... what would be the procedure in JMP Pro 14 for: 1. Calculate the probability of obtaining sales ..... for example less than US $ 500 or between US $ 500 and US $ 1,000 or more than US $ from US $ 1,000 2. How to pose and solve the classic problem of the "newspaper seller 3. How can you optimize the uncertainty or risk of selling products? Cheers,

On Wiki there is the following example:

This is the associated JSL code:

mu = 50;
sd = 20;
retailPrice = 7;
purchasePrice = 5;
quantity = normal quantile( (retailPrice-purchasePrice)/retailPrice, mu, sd);

This is the calculation for optimal quantity, not probability which is what you asked for, but maybe points you in the right direction.
