Hi guys I have this question as an assignment question can someone help out please thanks :)

Suppose you are at a casino playing roulette and that you are betting on black to turn up. You start by betting $1. If you win you bet another $1 in the next game. If you lose double your previous bet. You will stop playing when you have either won at least 10 or lost more than $100. By use of script file simulate this system.Then play the game 5000 times and record your performance.

Hint: use the command rand

Accepted answer

hi, try and verify this version:

N=5000; S=zeros(1,N); S(1)=1; % 1$

win=0; lost=0; threshold=0.5; for n=1:N-1

r=rand(); if r>=threshold win=win+1; S(n+1)=1+S(n); elseif r<threshold lost=lost+1; S(n+1)=S(n)-2; end if win>10 disp(' Congra! you won the game'); break; end if lost>50 disp(' You lost'); break; end end figure, plot(S(1:n)), title(' Game progress')
