Could someone please check my work?

If SCt), t20 is a geometric Brownian motion process with drift parameter M= 0. I and volatility parameter 0= 0.2, and P ( s ( 1 ) > scos ) is 0. 6915, what is P ( S ( 2 ) sco ) ) t= l log ($632 ) ~ N(MT , to ?) P ( s ca ) standard deviation of los ( sci =/1 (0. 2 2 ) = 0. 2 * = P ( Z s co ) ) = . 6915 ( . 30 8 5 ) 8 . 2133
