In hypothesis testing, this is the probability of failing to reject a false null hypothesis.
The distribution for a variable is the set of value that the variable can take and the probabilities associated with those value.
No. p-values are probabilities but they are not the only ones.
I do not add probabilities to anybody!

Standard & Poor's gives McDonald's beta as 1.32. Value Line says 0.75.
Beta measures a stock's volatility (the swings up and down in price). The market as a whole has a beta of 1.0, but each stock is determined a beta value from a history of it's stock movements. Riskiness equates to the stock losing value and high beta stocks are more prone to falling faster.
Sum of all probabilities is 1.
The beta of a portfolio is the weighted average of individual betas of assets in that portfolio. There is an example of portfolio beta calculation here: http://www.riskyreturn.com/portfolio_beta.html
