Let ( (\Omega, \mathcalF, P) ) be a probability space and ( X_1, X_2, \dots ) i.i.d. with ( E[X_1^+] = \infty ) and ( E[X_1^-] < \infty ). Show that ( \fracX_1 + \dots + X_nn \to \infty ) almost surely. advanced probability problems and solutions pdf

The intersection of $[0, 1]$ and $[z-1, z]$ is $[0, z]$. $$f_Z(z) = \int_0^z (1)(1) , dx = [x]_0^z = z$$ Pi=A+B(qp)icap P sub i equals cap A plus

cap P sub k equals p cap P sub k plus 1 end-sub plus q cap P sub k minus 1 end-sub 2. Define Boundary Conditions We know the outcome for certain at the limits of the game: If the gambler has , they have already lost: If the gambler has , they have already won: 3. Solve the Characteristic Equation The intersection of $[0, 1]$ and $[z-1, z]$ is $[0, z]$

P(X > 0.5) = ∫[0.5, 1] f(x) dx = ∫[0.5, 1] 1 dx = 0.5

$$J = \det \beginvmatrix \frac\partial x\partial r & \frac\partial x\partial \theta \ \frac\partial y\partial r & \frac\partial y\partial \theta \endvmatrix = \det \beginvmatrix \cos\theta & -r\sin\theta \ \sin\theta & r\cos\theta \endvmatrix = r\cos^2\theta + r\sin^2\theta = r$$ (Note: The absolute value of the Jacobian is $r$).
