First let y ∼ n(0,1) (a standard normal random variable), and then let x be the answer you get when you round y to the nearest integer. your answer does not need to be simplified to a number—you can write it with summations/fractions/integrals etc as needed. however, your final answer cannot have any probability type notation in it, e. g. it cannot include terms like px (3) or fy (1) or p (x ≤ 1) etc.
