%Probability distribution for a fair coin,Binomial Coefficients n=input('enter number of tosses:'); k=0:n;% the coin is tossed n times N=n*ones(1,n+1);% vectorizes n so we can do calculations a=factorial(N);% computes the factorial of each term in the vector N b=factorial(k);% computes the factorial of each term in the vector k c=factorial(N-k);%subtracts each elt of k from the corresponding elt of N and computes the factorial of each term in the new vector
