Is this homework? –  Louis Marascio Feb 11 at 15:28
    
@LouisMarascio Feels like it! But no it is not. –  ManInMoon Feb 11 at 15:48
    
If it is not homework, perhaps you want to share some more information, else why not just go with this? 1-pnorm((<end>-<start>)/100,mean=E(r_stock),sd=(<beta>*<vola>)) –  RndmSymbl Feb 11 at 20:27
    
@RndmSymbl Could you show me the worked out numbers step by step pls. –  ManInMoon Feb 12 at 7:22
    
@ManInMoon this question is better asked here: math.stackexchange.com/questions/339572/… And I have improved the answer there. –  RndmSymbl Feb 15 at 18:05
