Question 1: (a). Let Xt= the position (distance) of a particle at time t, with X0=0. Suppose the particle moves one step forward or backward with equal probability at each instant of time and successive steps are independent. If this movement is repeated many times, find the standard deviations of the distance Xt when t=1,2,3 showing your working.
