Brownian motion B: in discrete time over [0, 100] can be stimulated as follows: It Bi : 2K3 i=1 Where Y1, Y2, - - - , Y}; are independently and identically distributed normal N (0, 1). Use R to simulate Bt over [0, 100]. Include the point Bo = 0 on your line plot. Note: the following R command might be helpful > x
