Question

Write a program to simulate the flipping of three fair coins. Compute the number of times that all three coins come up the same in 1000 trials, and compare to the number of times you would expect. You may need to use

Explanation / Answer

function avgflips=coinflip(initP1,initP2,initP3,p,n) X =(rand(3,1)>p); count=zeros(n,1); for i=1:n playercoins=zeros(3,1); playercoins(1,1)=initP1; playercoins(2,1)=initP2; playercoins(3,1)=initP3; c=1; j=1; while j>0 if X(1,1)==X(2,1) && X(2,1)==X(3,1) playercoins=playercoins; elseif X(1,1)~=X(2,1) && X(1,1)~=X(3,1) && X(2,1)==X(2,1) playercoins=playercoins+[2;-1;-1]; elseif X(1,1)~=X(2,1) && X(1,1)==X(3,1) && X(2,1)~=X(3,1) playercoins=playercoins+[-1;2;-1]; elseif X(1,1)==X(2,1) && X(2,1)~=X(3,1) && X(1,1)~=X(3,1) playercoins=playercoins+[-1;-1;2]; end if playercoins(1,1)==0 j=0; elseif playercoins(2,1)==0 j=0; elseif playercoins(3,1)==0 j=0; end c=c+1; end count(i)=c; end avgflips=mean(count); end
