Can you pls focus on showing the excel calculation formula for the expected return of the portfolios and the Standard deviation of the portfolios?

2. Portfolio of assets with expected returns. There are four potential states of the economy for the coming year, and there are five potential assets for investing. First, find the expected return and the expected standard deviation of each of the five assets. Next, construct a set of portfolios with the weights listed in the second table for the assets in each portfolio. Find each portfolio's expected return and standard deviation. Determine the reduction in the standard deviation of the portfolio by comparing the weighted average standard deviation of the assets in the portfolio to the standard deviation of the portfolio.
