    Does this cover every topic needed for the final exam? Including combination/permutation, and other small sections?

    Who came with this concept?

    I don't think one specific person came up with the concept of statistic. It's a very useful branch of math, so I think people saw its application and developed different tools that help us answer important questions :)
