Write your drawframe function below
function drawframe(f)
close(gcf)
% Internal variables
n=1; % number of dice at each throw
f=n*f; % total number of dice thrown af each round/frame
s=6; % number of sides on dice
% Seed random generator and roll dice
rng(1);
rolls=randi([1,s],1,f); % vector of f dice rolls
counts=histcounts(rolls,1:s+1);
probs=counts/f; % probabilities/distributions of each roll value, expected to converge to 1/s (1/6)
% Top segment of figure for histogram of dice roll frequencies
subplot(4,1,1:3)
bar(probs)
