Due to uncertain economic conditions the owners of an independent bookstore estimate the following probabilities for moderate growth, the status quo and recession for next year and their associated profits for each scenario. What is their expected profit for next year? (Imagine this as a table) Growth, Probability, Estimated Profit Moderate Growth, 0.35, $250,000 Status Quo, .45, $200,000 Recession, .20, $100,000

    Expected profit is the goal, and luckily the owners of the bookstore have you given you probabilities for the profits to earn in each economic condition scenario

    Because the next year could enter either of the 3 economic condition scenarios, you will multiply each expected profit by its respective probability, then sum those 3 values to obtain the expected profit for the next year.

    Because you dealing with expectations. This idea of expected value is prominent in finance and economics. Because there are 3 ways the economy could go: moderate growth, recession, status quo, you also don't know which of the 3 ways will be the true way. So, there is probability assigned to each way. If things go to moderate growth, then you will definitely make $250,000 If things go to status quo, then you will definitely make $200,000 If things go to recession, then you will definitely make $100,000 But these are all conditionals.

    Right, so to imagine the profit you will make while considering the 3 directions of the economy, you sum up the profits multiplied by their respective probabilities of economic direction. No problem, glad to help

    consider your table as a probability mass function,the question is asking for the expected profit or in other words the expected mean given by the formula below
