back to [[Statistics/Assumptions]] When we assert that two or more [[Random Variables]] are independent, we imply that probabilities of compound events involving these variables can be calculated by simply multiplying the probabilities of the individual events. *Pr[(X in A) & (Y in B)] = Pr[X in A]*Pr[Y in B] *fXY(x,y)dx dy = fX(x)dx fY(y)dy where f represents a density and the indices on f indicate the random variable. ---- [[Dick Beldin]]
