- Let P be the standard normal distribution, i.e., P is the proba-bility measure on R, B(R) given bydP(x) = 1√2πe− x2/2dx.Consider the random variablesfn(x) = (1 + x2) 1/ne^(x^2/n+2) x ∈ R, n ∈ N.Using the dominated convergence theorem, prove that the limitlimn→∞E(fn)exists and find itarrow_forward13) Consider the checkerboard arrangement shown below. Assume that the red checker can move diagonally upward, one square at a time, on the white squares. It may not enter a square if occupied by another checker, but may jump over it. How many routes are there for the red checker to the top of the board?arrow_forward12) The prime factors of 1365 are 3, 5, 7 and 13. Determine the total number of divisors of 1365.arrow_forward
