Determines k:

b) represent event ''B given A'' on D calculate the probability.

c) establish if X and Y are independent.

d) give the expectation and variance of X and Y.

e) calculate the covariance Cov(X,Y) and the coefficient and correlation p(X,Y) Comment on the relationship between X and Y.

 

kry = {ko f(x, y) = 0 (x,y) D ailleurs pour D = {(x, y)|0 x 2 et 1 y 2z} On a les vnements A = {(x, y) = D1-1 1 et 2
