children can compute the probabilities of the various outcomes by going to the seventh row and adding up the numbers (which yields 64) and dividing each number by the total. There is only a 1/64 chance that this couple will have six boys (or six girls), a 6/64 chance of having five boys and a girl (or five girls and a boy) and so on.

The CAPM formula is: Cost of Equity (Ke) = rf + β (Rm – Rf) CAPM establishes the relationship between the risk-return profile of a security (or portfolio) based on three variables: the risk-free rate (rf), the beta (β) of the underlying security, and the equity risk premium (ERP). CAPM calculates the cost of equity (Ke), or expected return ... Compute beta estimates for multi-factor models such as the Fama-French 3 factor model. For that purpose, you extend your regression to r i, t − r f, t = α i + ∑ j = 1 k β i, k ( r j, t − r f, t) + ε i, t where r j, t are the k factor returns. Thus, you estimate 4 parameters ( α i and the slope coefficients).You can compute it using this formula: Beta = Cov(r s, r m) σ 2 m. where: Cov = refers to the Covariance of the Stock Market. r s = refers to the Stock Return. r m = refers to the Market Return. σ 2 m = refers to the Market Variance.

William Sharpe, one of the scholars who came up with the ideas of alpha and beta, put his faith in high-beta securities because of this belief. Because the sum of all alphas of all portfolios has to be zero, and because he believed in an efficient market, he and his colleagues effectively rewrote y = α + βx as y = βx.
